+form of custom URL resolvers.

+    """Element generator factory.
+
+    Unlike the ordinary Element factory, the E factory allows you to pass in
+    more than just a tag and some optional attributes; you can also pass in
+    text and other elements.  The text is added as either text or tail
+    attributes, and elements are inserted at the right spot.  Some small
+    examples::
+
+        >>> from lxml import etree as ET
+        >>> from lxml.builder import E
+
+        >>> ET.tostring(E("tag"))
+        '<tag/>'
+        >>> ET.tostring(E("tag", "text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E("tag", "text", key="value"))
+        '<tag key="value">text</tag>'
+        >>> ET.tostring(E("tag", E("subtag", "text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    For simple tags, the factory also allows you to write ``E.tag(...)`` instead
+    of ``E('tag', ...)``::
+
+        >>> ET.tostring(E.tag())
+        '<tag/>'
+        >>> ET.tostring(E.tag("text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E.tag(E.subtag("text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    Here's a somewhat larger example; this shows how to generate HTML
+    documents, using a mix of prepared factory functions for inline elements,
+    nested ``E.tag`` calls, and embedded XHTML fragments::
+
+        # some common inline elements
+        A = E.a
+        I = E.i
+        B = E.b
+
+        def CLASS(v):
+            # helper function, 'class' is a reserved word
+            return {'class': v}
+
+        page = (
+            E.html(
+                E.head(
+                    E.title("This is a sample document")
+                ),
+                E.body(
+                    E.h1("Hello!", CLASS("title")),
+                    E.p("This is a paragraph with ", B("bold"), " text in it!"),
+                    E.p("This is another paragraph, with a ",
+                        A("link", href="http://www.python.org"), "."),
+                    E.p("Here are some reserved characters: <spam&egg>."),
+                    ET.XML("<p>And finally, here is an embedded XHTML fragment.</p>"),
+                )
+            )
+        )
+
+        print ET.tostring(page)
+
+    Here's a prettyprinted version of the output from the above script::
+
+        <html>
+          <head>
+            <title>This is a sample document</title>
+          </head>
+          <body>
+            <h1 class="title">Hello!</h1>
+            <p>This is a paragraph with <b>bold</b> text in it!</p>
+            <p>This is another paragraph, with <a href="http://www.python.org">link</a>.</p>
+            <p>Here are some reserved characters: &lt;spam&amp;egg&gt;.</p>
+            <p>And finally, here is an embedded XHTML fragment.</p>
+          </body>
+        </html>
+
+    For namespace support, you can pass a namespace map (``nsmap``)
+    and/or a specific target ``namespace`` to the ElementMaker class::
+
+        >>> E = ElementMaker(namespace="http://my.ns/")
+        >>> print(ET.tostring( E.test ))
+        <test xmlns="http://my.ns/"/>
+
+        >>> E = ElementMaker(namespace="http://my.ns/", nsmap={'p':'http://my.ns/'})

+lxml-based doctest output comparison.
+
+Note: normally, you should just import the `lxml.usedoctest` and
+`lxml.html.usedoctest` modules from within a doctest, instead of this
+one::
+
+    >>> import lxml.usedoctest # for XML output
+
+    >>> import lxml.html.usedoctest # for HTML output
+
+To use this module directly, you must call ``lxmldoctest.install()``,
+which will cause doctest to use this in all subsequent calls.
+
+This changes the way output is checked and comparisons are made for
+XML or HTML-like content.
+
+XML or HTML content is noticed because the example starts with ``<``
+(it's HTML if it starts with ``<html``).  You can also use the
+``PARSE_HTML`` and ``PARSE_XML`` flags to force parsing.
+
+Some rough wildcard-like things are allowed.  Whitespace is generally
+ignored (except in attributes).  In text (attributes and text in the
+body) you can use ``...`` as a wildcard.  In an example it also
+matches any trailing tags in the element, though it does not match
+leading tags.  You may create a tag ``<any>`` or include an ``any``
+attribute in the tag.  An ``any`` tag matches any tag, while the
+attribute matches any and all attributes.
+
+When a match fails, the reformatted example and gotten text is
+displayed (indented), and a rough diff-like output is given.  Anything
+marked with ``+`` is in the output but wasn't supposed to be, and
+similarly ``-`` means its in the example but wasn't in the output.
+
+You can disable parsing on one line with ``# doctest:+NOPARSE_MARKUP``

+    Instances cleans the document of each of the possible offending
+    elements.  The cleaning is controlled by attributes; you can
+    override attributes in a subclass, or set them in the constructor.
+
+    ``scripts``:
+        Removes any ``<script>`` tags.
+
+    ``javascript``:
+        Removes any Javascript, like an ``onclick`` attribute. Also removes stylesheets
+        as they could contain Javascript.
+
+    ``comments``:
+        Removes any comments.
+
+    ``style``:
+        Removes any style tags.
+
+    ``inline_style``
+        Removes any style attributes.  Defaults to the value of the ``style`` option.
+
+    ``links``:
+        Removes any ``<link>`` tags
+
+    ``meta``:
+        Removes any ``<meta>`` tags
+
+    ``page_structure``:
+        Structural parts of a page: ``<head>``, ``<html>``, ``<title>``.
+
+    ``processing_instructions``:
+        Removes any processing instructions.
+
+    ``embedded``:
+        Removes any embedded objects (flash, iframes)
+
+    ``frames``:
+        Removes any frame-related tags
+
+    ``forms``:
+        Removes any form tags
+
+    ``annoying_tags``:
+        Tags that aren't *wrong*, but are annoying.  ``<blink>`` and ``<marquee>``
+
+    ``remove_tags``:
+        A list of tags to remove.  Only the tags will be removed,
+        their content will get pulled up into the parent tag.
+
+    ``kill_tags``:
+        A list of tags to kill.  Killing also removes the tag's content,
+        i.e. the whole subtree, not just the tag itself.
+
+    ``allow_tags``:
+        A list of tags to include (default include all).
+
+    ``remove_unknown_tags``:
+        Remove any tags that aren't standard parts of HTML.
+
+    ``safe_attrs_only``:
+        If true, only include 'safe' attributes (specifically the list
+        from the feedparser HTML sanitisation web site).
+
+    ``safe_attrs``:
+        A set of attribute names to override the default list of attributes
+        considered 'safe' (when safe_attrs_only=True).
+
+    ``add_nofollow``:
+        If true, then any <a> tags will have ``rel="nofollow"`` added to them.
+
+    ``host_whitelist``:
+        A list or set of hosts that you can use for embedded content
+        (for content like ``<object>``, ``<link rel="stylesheet">``, etc).
+        You can also implement/override the method
+        ``allow_embedded_url(el, url)`` or ``allow_element(el)`` to
+        implement more complex rules for what can be embedded.
+        Anything that passes this test will be shown, regardless of
+        the value of (for instance) ``embedded``.
+
+        Note that this parameter might not work as intended if you do not
+        make the links absolute before doing the cleaning.
+
+        Note that you may also need to set ``whitelist_tags``.
+
+    ``whitelist_tags``:
+        A set of tags that can be included with ``host_whitelist``.
+        The default is ``iframe`` and ``embed``; you may wish to
+        include other tags like ``script``, or you may want to
+        implement ``allow_embedded_url`` for more control.  Set to None to

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip and raw deflate streams in
+  memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in the case of corrupted input.

+
+     On 16-bit systems, the functions zalloc and zfree must be able to allocate

+   any allocation of 64K objects, at the expense of compression ratio, compile
+   the library with -DMAX_WBITS=14 (see zconf.h).
+
+     The fields total_in and total_out can be used for statistics or progress
+   reports.  After compression, total_in holds the total size of the
+   uncompressed data and may be saved for use by the decompressor (particularly
+   if the decompressor wants to decompress everything in a single step).

+/*
+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary.  Some output may be provided even if
+    flush is zero.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending. See deflatePending(),
+  which can be used if desired to determine whether or not there is more ouput
+  in that case.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed
+  codes block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
+  function must be called again with Z_FINISH and more output space (updated
+  avail_out) but no more input data, until it returns with Z_STREAM_END or an
+  error.  After deflate has returned Z_STREAM_END, the only possible operations
+  on the stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used in the first deflate call after deflateInit if all the
+  compression is to be done in a single step.  In order to complete in one
+  call, avail_out must be at least the value returned by deflateBound (see
+  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
+  output space is provided, deflate will not return Z_STREAM_END, and it must
+  be called again as described above.
+
+    deflate() sets strm->adler to the Adler-32 checksum of all input read
+  so far (that is, total_in bytes).  If a gzip stream is being generated, then

+
+    deflate() may update strm->data_type if it can make a good guess about

+  considered binary.  This field is only for information purposes and does not
+  affect the compression algorithm in any manner.
+

+ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
+/*
+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), then next_in and avail_in are updated
+    accordingly, and processing will resume at this point for the next call of
+    inflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  If the
+  caller of inflate() does not provide both available input and available
+  output space, it is possible that there will be no progress made.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  To assist in this, on return inflate() always sets strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.)  The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed Adler-32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained unless inflateGetHeader() is used.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
+  uncompressed length, modulo 2^32.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value, in which case strm->msg points to a string with a more specific
+  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL, or the state was inadvertently written over
+  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
+  if no progress was possible or if there was not enough room in the output
+  buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is to be attempted.

+
+     This is another version of deflateInit with more compression options.  The
+   fields zalloc, zfree and opaque must be initialized before by the caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     For the current implementation of deflate(), a windowBits value of 8 (a
+   window size of 256 bytes) is not supported.  As a result, a request for 8
+   will result in 9 (a 512-byte window).  In that case, providing 8 to
+   inflateInit2() will result in an error when the zlib header with 9 is
+   checked against the initialization of inflate().  The remedy is to not use 8
+   with deflateInit2() with this initialization, or at least in that case use 9
+   with inflateInit2().
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute a check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to the appropriate value,
+   if the operating system was determined at compile time.  If a gzip stream is
+   being written, strm->adler is a CRC-32 instead of an Adler-32.
+
+     For raw deflate or gzip encoding, a request for a 256-byte window is
+   rejected as invalid, since only the zlib header provides a means of
+   transmitting the window size to the decompressor.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
+   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
+   set to null if there is no error message.  deflateInit2 does not perform any
+   compression: this will be done by deflate().

+   compressor and decompressor must use exactly the same dictionary (see

+
+     The dictionary should consist of strings (byte sequences) that are likely

+
+     This is another version of inflateInit with an extra parameter.  The
+   fields next_in, avail_in, zalloc, zfree and opaque must be initialized
+   before by the caller.
+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library.  The default value is 15 if inflateInit is used
+   instead.  windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used.  If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be zero to request that inflate use the window size in
+   the zlib header of the compressed stream.
+
+     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
+   determines the window size.  inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream.  This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values.  If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is.  Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding.  Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will
+   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
+   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
+   below), inflate() will *not* automatically decode concatenated gzip members.
+   inflate() will return Z_STREAM_END at the end of the gzip member.  The state
+   would need to be reset to continue decoding a subsequent gzip member.  This
+   *must* be done if there is more data after a gzip member, in order for the
+   decompression to be compliant with the gzip standard (RFC 1952).
+
+     inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+   invalid, such as a null pointer to the structure.  msg is set to null if
+   there is no error message.  inflateInit2 does not perform any decompression
+   apart from possibly reading the zlib header if present: actual decompression
+   will be done by inflate().  (So next_in and avail_in may be modified, but

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the default
+   behavior of inflate(), which expects a zlib header and trailer around the
+   deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero -- buf is ignored in that
+   case -- and inflateBack() will return a buffer error.  inflateBack() will
+   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+   out() should return zero on success, or non-zero on failure.  If out()
+   returns non-zero, inflateBack() will return with an error.  Neither in() nor
+   out() are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.)  Note that inflateBack()

+    """An ISO Schematron validator.
+
+    Pass a root Element or an ElementTree to turn it into a validator.
+    Alternatively, pass a filename as keyword argument 'file' to parse from
+    the file system.
+
+    Schematron is a less well known, but very powerful schema language.
+    The main idea is to use the capabilities of XPath to put restrictions on
+    the structure and the content of XML documents.
+
+    The standard behaviour is to fail on ``failed-assert`` findings only
+    (``ASSERTS_ONLY``).  To change this, you can either pass a report filter
+    function to the ``error_finder`` parameter (e.g. ``ASSERTS_AND_REPORTS``
+    or a custom ``XPath`` object), or subclass isoschematron.Schematron for
+    complete control of the validation process.
+
+    Built on the Schematron language 'reference' skeleton pure-xslt
+    implementation, the validator is created as an XSLT 1.0 stylesheet using
+    these steps:
+
+     0) (Extract from XML Schema or RelaxNG schema)
+     1) Process inclusions
+     2) Process abstract patterns
+     3) Compile the schematron schema to XSLT
+
+    The ``include`` and ``expand`` keyword arguments can be used to switch off
+    steps 1) and 2).
+    To set parameters for steps 1), 2) and 3) hand parameter dictionaries to the
+    keyword arguments ``include_params``, ``expand_params`` or
+    ``compile_params``.
+    For convenience, the compile-step parameter ``phase`` is also exposed as a
+    keyword argument ``phase``. This takes precedence if the parameter is also
+    given in the parameter dictionary.
+
+    If ``store_schematron`` is set to True, the (included-and-expanded)
+    schematron document tree is stored and available through the ``schematron``
+    property.
+    If ``store_xslt`` is set to True, the validation XSLT document tree will be
+    stored and can be retrieved through the ``validator_xslt`` property.
+    With ``store_report`` set to True (default: False), the resulting validation
+    report document gets stored and can be accessed as the ``validation_report``
+    property.
+
+    Here is a usage example::

+     OVERVIEW - iso_abstract_expand.xsl
+     
+	    This is a preprocessor for ISO Schematron, which implements abstract patterns. 
+	    It also 
+	       	* extracts a particular schema using an ID, where there are multiple 
+             schemas, such as when they are embedded in the same NVDL script 
+           * allows parameter substitution inside @context, @test, @select, @path
+	    	   * experimentally, allows parameter recognition and substitution inside
+             text (NOTE: to be removed, for compataibility with other implementations,   
+             please do not use this) 
+		
+		This should be used after iso-dsdl-include.xsl and before the skeleton or
+		meta-stylesheet (e.g. iso-svrl.xsl) . It only requires XSLT 1.
+		 
+		Each kind of inclusion can be turned off (or on) on the command line.

+<!-- 
+     OVERVIEW : iso_dsdl_include.xsl
+     
+	    This is an inclusion preprocessor for the non-smart text inclusions
+	    of ISO DSDL. It handles 
+	    	<relax:extRef> for ISO RELAX NG
+	    	<sch:include>  for ISO Schematron and Schematron 1.n
+	    	<sch:extends>  for 2009 draft ISO Schematron
+	    	<xi:xinclude>  simple W3C XIncludes for ISO NVRL and DSRL 
+	    	<crdl:ref>     for draft ISO CRDL
+	    	<dtll:include> for draft ISO DTLL
+	    	<* @xlink:href> for simple W3C XLink 1.1 embedded links
+	    	
+		 
+		This should be the first in any chain of processing. It only requires
+		XSLT 1. Each kind of inclusion can be turned off (or on) on the command line.
+		
+		Ids in fragment identifiers or xpointers will be sought in the following
+		order:
+		    * @xml:id
+		    * id() for typed schemas (e.g. from DTD) [NOTE: XInclude does not support this]
+		    * untyped @id 
+		    
+	The proposed behaviour for the update to ISO Schematron has been implemented. If an
+	include points to an element with the same name as the parent, then that element's
+	contents will be included. This supports the merge style of inclusion.    
+	
+	When an inclusion is made, it is preceded by a PI with target DSDL_INCLUDE_START
+	and the href and closed by a PI with target DSDL_INCLUDE_START and the href. This is
+	to allow better location of problems, though only to the file level. 
+	
+	Limitations:
+	* No rebasing: relative paths will be interpreted based on the initial document's

+<!-- 
+  VERSION INFORMATION
+	2009-02-25 
+	* Update DSDL namespace to use schematron.com
+	* Tested with SAXON9, Xalan 2.7.1, IE7, 
+	* IE does not like multiple variables in same template with same name: rename.   
+	2008-09-18
+	* Remove new behaviour for include, because it conflicts with existing usage [KH]
+	* Add extends[@href] element with that merge functionality
+	* Generate PIs to notate source of inclusions for potential better diagnostics
+	
+	2008-09-16
+	* Fix for XSLT1
+	
+	2008-08-28
+	* New behaviour for schematron includes: if the pointed to element is the same as the current,
+	include the children.
+	
+	2008-08-20
+	* Fix bug: in XSLT1 cannot do $document/id('x') but need to use for-each
+	
+	2008-08-04
+	* Add support for inclusions in old namespace  
+	
+	2008-08-03
+	* Fix wrong param name include-relaxng & include-crdl (KH, PH)
+	* Allow inclusion of XSLT and XHTML (KH)
+	* Fix inclusion of fragments (KH)
+	
+	2008-07-25
+	* Add selectable input parameter
+	
+	2008-07-24

+   OVERVIEW
+   
+   ASCC/Schematron.com Skeleton Module for ISO Schematron (for XSLT1 systems)
+   
+   ISO Schematron is a language for making assertion about the presence or absence
+   of patterns in XML documents. It is typically used for as a schema language, or
+   to augment existing schema languages, and to check business rules. It is very
+   powerful, yet quite simple: a developer only need know XPath and about five other
+   elements.
+   
+   This is an open source implementation of ISO Schematron in XSLT. Although ISO does
+   not allow reference implementations which might compete with the text of the
+   standard, this code has been compiled by Rick Jelliffe, inventor of Schematron
+   and editor of the ISO standard; so developers can certainly use it as an 
+   unofficial reference implementation for clarification. 
+   
+   This implementation is based on one by Oliver Becker. API documentation is 
+   available separately; try www.schematron.com for this. Funding for this
+   stylesheet over the years has come from Topologi Pty. Ltd., Geotempo Ltd.,
+   and ASCC, Tapei.
+   
+   There are two versions of this skeleton: one is tailored for XSLT1 processors
+   and the other is tailored for XSLT2 processors. Future versions of the
+   XSLT2 skeleton may support more features than that the XSLT 1 skeleton.

+   TIPS
+      
+   A tip for new users of Schematron: make your assertions contain positive messages
+   about what is expected, rather than error messages. For example, use the form
+   "An X should have a Y, because Z". 
+   
+   Another tip is that Schematron provides an
+   element <sch:ns> for declaring the namespaces and prefixes used in Xpaths in 
+   attribute values; it does not extend the XML Namespaces mechanism: if a name
+   in an XPath has a prefix, there must be an <sch:ns> element for that prefix; if
+   a name in an XPath does not have a prefix, it is always in no namespace.
+   
+   A tip for implementers of Schematron, either using this API or re-implementing it:
+   make the value of the diagnostics, flags and richer features available if possible;
+   Schematron has many of the optional richer features which, if implemented, provide
+   a compelling alternative approach to validation and business-rules checking compared
+   to other schema languages and programs. 
+   
+   If you create your own meta-stylesheet to override this one, it is a
+   good idea to have both in the same directory and to run the stylesheet
+   from that directory, as many XSLT implementations have ideosyncratic
+   handling of URLs: keep it simple.

+  XSLT 1:
+     A schema using the standard XSLT 1 query binding will have a /schema/@queryBinding='xslt' or 
+     nothing.
+
+       * Note: XT does not implement key() and will die if given it. 
+       * Add all formal parameters to default templates

+  EXSLT:  Experimental support
+     A schema using the EXSLT query binding will have a /schema/@queryBinding='exslt'.
+     It is built on XSLT 1. After experience is gained, this binding is expected to be 
+     formalized as part of ISO Schematron, which currently reserves the "exslt" name for this purpose.
+
+     Some EXSLT engines have the extra functions built-in. For these, there is no need to
+     provide library locations. For engines that require the functions, either hard code
+     them in this script or provide them on the command-line argument.

+<!--
+   PROCESS INFORMATION
+   
+   This stylesheet compiles a Schematron schema (*.sch) into XSLT code (*.xsl). 
+   The generated XSLT code can then be run against an XML file (*.xml, etc) and
+   will produce validation results.
+   
+   The output of validation results is performed using named templates (process-*). 
+   These can be overridden easily by making a new XSLT stylesheet that imports this 
+   stylesheet but has its own version of the relevant process-* templates. Several
+   of these invoking stylesheets are available: "iso_svrl.xsl", for example generates
+   ISO Schematron Validation Report Language format results.
+   
+   In this version of the stylesheet, the ISO feature called "abstract patterns" is
+   implemented using macro processing: a prior XSLT stage to which converts uses
+   of abstract patterns into normal patterns. If you do not use abstract patterns,
+   it is not necessary to preprocess the schema.
+   
+   To summarize, a basic process flow for some commandline processor is like this:
+     XSLT -input=xxx.sch  -output=xxx.xsl  -stylesheet=iso_schematron_skeleton.xsl
+     XSLT -input=document.xml  -output=xxx-document.results  -stylesheet=xxx.xsl
+   
+   iso_svrl.xslt is an implementation of Schematron that can use this skeleton and
+   generate ISO SVRL reports. A process flow for some commandline processor would
+   be like this:
+     XSLT -input=xxx.sch  -output=xxx.xsl  -stylesheet=iso_svrl.xsl
+     XSLT -input=document.xml  -output=xxx-document.results  -stylesheet=xxx.xsl
+     
+   It is not impossible that ultimately a third stage, to handle macro-preprocessing
+   and inclusion, might be necessary. (The trade-off is in making this XSLT more
+   complex compared to making the outer process more complex.)
+             
+  This version has so far been tested with
+     Saxon 8
+     MSXML 4 (or 6?)   
+
+ Please note that if you are using SAXON and JAXP, then you should use 
+  System.setProperty("javax.xml.transform.TransformerFactory",
+                          "net.sf.saxon.TransformerFactoryImpl");
+ rather than 
+  System.setProperty("javax.xml.xpath.TransformerFactory",
+                           "net.sf.saxon.TransformerFactoryImpl");
+ which is does not work, at least for the versions of SAXON we tried.

+
+  VERSION INFORMATION 
+   2009-02-25 RJ
+        * Fix up variable names so none are used twice in same template
+        * Tested on SAXON 9, Xalan 2.7.1. Partly tested MSXML.  
+   2008-09-19 RJ
+        * Add mode schematron-select-full-path and param full-path-notation 
+   
+   2008-08-11
+   		* TT report/@flag was missing
+   2008-08-06
+   		* TT Top-level lets need to be implemented using xsl:param not xsl:variable
+   		* TT xsl:param/@select must have XPath or not be specified
+   		
+    Version: 2008-07-28
+   		* KH schematron-get-full-path-3 has [index] even on top step
+   		* RJ fix schematron-get-full-path to have namespace predicate, I don't know why this was removed
+   		
+   Version: 2008-07-24
+   		* RJ clean out commented out namespace handling code
+   		* RJ add support for experimental non-standard attribute report/@action
+   		and assert/@action, and add parameter not in the published API (should
+   		not break anything, it is XSLT1)
+   		* RJ Remove remaining XSLT2 code for ease of reading
+   		
+   Version: 2008-07-14 minor update for inclusion experiments
+   	* RJ Clean up zero-length fragment test on include
+   	* RJ Add experimental support for include containers 
+   	* RJ For path generation, test for //iso:schema not just /iso:schema, for potential embedded Schematron support   
+   	* RJ Don't generate double error messages for old namespace elements
+   	* RJ Experimental iso:rule/iso:title just kept as comment (bigger request Uche Ogbuji)
+   	* RJ Remove spurious debug messages
+   	* RJ Fix bug that prevented including patterns in this (report Roger
+   	Costello)
+  
+   Version: 2007-10-17
+     From this version on I am forking XSLT2 support to a different version of the script.
+     This is due to the increasingly horrible state of the namespace handling code as well
+     as other inconsistencies between the major implementations of different versions.
+     The intent is that future versions of this will have XSLT2 isms removed and be simplified
+     to cope with only XSLT1 and EXLST. Note that though this version is called
+     iso_schematron_skeleton_for_xslt1, the various meta-stylesheets will continue to just call
+     iso_schematron_skeleton: it is up to you to rename the stylesheet to the one you want to
+     use.
+
+       * RJ fix FULL-PATH problem with attribute names
+
+
+   Version: 2007-07-19

+    		
+    
+   Version: 2007-04-04
+   	* RJ debug mode param
+	* RJ alter mixed test to only test mixed branches, so the same document

+	* SB add hint on SAXON and JAXP

+   		  Move process-ns to outside the stylesheet body.
+   		* DP, FG, fix handling of xslt:key
+   		* FG no iso:title/@class
+   		* Experimental optimization 'visit-no-attributes'

+ 		* DC Move stylesheet/@version generation to after namespace handling
+ 		* DC, FG EXSLT namespace handling code

+          * Extra comments on the different queryBindings
+          * KH Add option "message-paths" to generate XPath from output 
+          * KH Add option "terminate" to halt with an error after the first assertion

+
+    
+    KNOWN TYPICAL LIMITATIONS:
+      * Don't use <sch:ns prefix="xsl" .../> with a namespace other than the standard
+      XSLT one. This would be a bizarre thing to do anyway. 
+      * Don't use other prefixes for the XSLT namespace either; some implementations will
+      not handle it correctly.
+     
+     EXTENSIONS:
+      ISO Schematron is designed as a framework with some standard query language
+      bindings. If you need to support other features, please do so safely by making
+      up your own @queryLanguage name: this makes it clear that your schema requires
+      special features. For example, default ISO Schematron does not support user
+      defined functions; so if you want to use the user defined function feature
+      in XSLT, you need to have a schema with some queryBinding attribute name like
+      "XSLT-with-my-functions" or whatever.

+	     
+	     XT, the early XSLT processor, did not implement key and died when it was present.

+	     "key". This has been removed.

+
+   Implementation of Schematron Validation Report Language from ISO Schematron
+   ISO/IEC 19757 Document Schema Definition Languages (DSDL) 
+     Part 3: Rule-based validation  Schematron 
+     Annex D: Schematron Validation Report Language 
+
+  This ISO Standard is available free as a Publicly Available Specification in PDF from ISO.
+  Also see www.schematron.com for drafts and other information.
+
+  This implementation of SVRL is designed to run with the "Skeleton" implementation 
+  of Schematron which Oliver Becker devised. The skeleton code provides a 
+  Schematron implementation but with named templates for handling all output; 
+  the skeleton provides basic templates for output using this API, but client
+  validators can be written to import the skeleton and override the default output
+  templates as required. (In order to understand this, you must understand that
+  a named template such as "process-assert" in this XSLT stylesheet overrides and
+  replaces any template with the same name in the imported skeleton XSLT file.)
+
+  The other important thing to understand in this code is that there are different
+  versions of the Schematron skeleton. These track the development of Schematron through
+  Schematron 1.5, Schematron 1.6 and now ISO Schematron. One only skeleton must be
+  imported. The code has templates for the different skeletons commented out for 
+  convenience. ISO Schematron has a different namespace than Schematron 1.5 and 1.6;
+  so the ISO Schematron skeleton has been written itself with an optional import
+  statement to in turn import the Schematron 1.6 skeleton. This will allow you to 
+  validate with schemas from either namespace.
+  
+
+  History:  
+    2009-03-18
+    	* Fix atrribute with space "see " which generates wrong name in some processors
+    2008-08-11
+   		* RJ Fix attribute/@select which saxon allows  in XSLT 1
+   2008-08-07
+    	* RJ Add output-encoding attribute to specify final encoding to use
+    	* Alter allow-foreign functionality so that Schematron span, emph and dir elements make 
+    	  it to the output, for better formatting and because span can be used to mark up
+    	  semantically interesting information embedded in diagnostics, which reduces the
+    	  need to extend SVRL itself
+    	* Diagnostic-reference had an invalid attribute @id that duplicated @diagnostic: removed
+  	2008-08-06
+    	* RJ Fix invalid output:  svrl:diagnostic-reference is not contained in an svrl:text
+    	* Output comment to SVRL file giving filename if available (from command-line parameter)
+  	2008-08-04
+  		* RJ move sch: prefix to schold: prefix to prevent confusion (we want people to
+  		be able to switch from old namespace to new namespace without changing the
+  		sch: prefix, so it is better to keep that prefix completely out of the XSLT)
+  		* Extra signature fixes (PH)
+    2008-08-03
+    	* Repair missing class parameter on process-p
+    2008-07-31
+    	* Update skeleton names
+    2007-04-03 
+    	* Add option generate-fired-rule (RG)
+    2007-02-07
+    	* Prefer true|false for parameters. But allow yes|no on some old for compatability
+    	* DP Diagnostics output to svrl:text. Diagnosis put out after assertion text.
+      	* Removed non-SVRL elements and attributes: better handled as an extra layer that invokes this one
+      	* Add more formal parameters
+      	* Correct confusion between $schemaVersion and $queryBinding
+     	* Indent
+     	* Validate against RNC schemas for XSLT 1 and 2 (with regex tests removed)
+     	* Validate output with UniversalTest.sch against RNC schema for ISO SVRL
+    	
+    2007-02-01
+       	* DP. Update formal parameters of overriding named templates to handle more attributes.
+       	* DP. Refactor handling of rich and linkable parameters to a named template.
+
+    2007-01-22
+    	* DP change svrl:ns to svrl:ns-in-attribute-value
+		* Change default when no queryBinding from "unknown" to "xslt"
+	
+    2007-01-18:
+     	* Improve documentation
+     	* KH Add command-line options to generate paths or not 
+       	* Use axsl:attribute rather than xsl:attribute to shut XSLT2 up
+       	* Add extra command-line options to pass to the iso_schematron_skeleton
+  
+    2006-12-01: iso_svrl.xsl Rick Jelliffe, 
+          * update namespace, 
+          * update phase handling,
+          * add flag param to process-assert and process-report & @ flag on output
+  
+    2001: Conformance1-5.xsl Rick Jelliffe, 
+          * Created, using the skeleton code contributed by Oliver Becker

+ISO SCHEMATRON 2010

+

+XSLT implementation by Rick Jelliffe with assistance from members of Schematron-love-in maillist.

+

+2010-04-21

+

+Two distributions are available. One is for XSLT1 engines. 

+The other is for XSLT2 engines, such as SAXON 9.

+

+

+This version of Schematron splits the process into a pipeline of several different XSLT stages.

+

+1) First, preprocess your Schematron schema with iso_dsdl_include.xsl.  

+This is a macro processor to assemble the schema from various parts. 

+If your schema is not in separate parts, you can skip this stage.

+This stage also generates error messages for some common XPath syntax problems.

+

+2) Second, preprocess the output from stage 1 with iso_abstract_expand.xsl.  

+This is a macro processor to convert abstract patterns to real patterns. 

+If your schema does not use abstract patterns, you can skip this

+stage.

+

+3) Third, compile the Schematron schema into an XSLT script. 

+This will typically use iso_svrl_for_xslt1.xsl or iso_svrl_for_xslt2.xsl 

+(which in turn invoke iso_schematron_skeleton_for_xslt1.xsl or iso_schematron_skeleton_for_saxon.xsl)

+However, other "meta-stylesheets" are also in common use; the principle of operation is the same.

+If your schema uses Schematron phases, supply these as command line/invocation parameters

+to this process.

+

+4) Fourth, run the script generated by stage 3 against the document being validated.

+If you are using the SVRL script, then the output of validation will be an XML document.

+If your schema uses Schematron parameters, supply these as command line/invocation parameters

+to this process. 

+

+

+The XSLT2 distribution also features several next generation features, 

+such as validating multiple documents. See the source code for details.

+

+Schematron assertions can be written in any language, of course; the file

+sch-messages-en.xhtml contains the diagnostics messages from the XSLT2 skeleton

+in English, and this can be used as template to localize the skeleton's

+error messages. Note that typically programming errors in Schematron are XPath

+errors, which requires localized messages from the XSLT engine.

+

+ANT

+---

+To give an example of how to process a document, here is a sample ANT task.
