+    """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/"/>

+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``

+    """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.
+
+    If ``validate_schema`` is set to False, the validation of the schema file
+    itself is disabled.  Validation happens by default after building the full
+    schema, unless the schema validation file cannot be found at import time,
+    in which case the validation gets disabled.  Some lxml distributions exclude
+    this file due to licensing issues.  ISO-Schematron validation can then still
+    be used normally, but the schemas themselves cannot be validated.

+     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
+	path, not the including document. (Severe limitation!)
+	* No checking for circular references
+	* Not full xpointers: only ID matching
+	* <relax:include> not implemented 
+	* XInclude handling of xml:base and xml:lang not implemented   
+-->
+<!-- 
+  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  
+	* RJ New

+   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 VERSION SUPPORT
+
+  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
+       * Fix missing apply-templates from process-ns and add params back
+
+  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.

+  NOTE: Compared to the iso_schematron_skeleton_for_saxon.xsl code, this version is currently missing

+     2) properties
+     3) pattern/@documents
+
+  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

+    	nodes too for context 
+    	* DPC Fix inclusion syntax to allow #
+    	* DPC Priorities count up from 1000 not down from 4000 to allow more rules

+        Override process-schema-title for custom processing of title
+    		
+    
+   Version: 2007-04-04
+   	* RJ debug mode param
+	* RJ alter mixed test to only test mixed branches, so the same document
+	could have old and new namespaces schemas in it, but each schema must
+	be distinct, just so as not to overconstrain things.
+   	* KH zero-length include/@href is fatal error, but allow debug mode
+	* SB add hint on SAXON and JAXP
+	* DC generate-full-path-1 generates XLST1 code by default

+   		  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'

+          * 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.

+
+   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"
+

+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.
+

+
+    Incremental parser.
+
+    Parses XML into a tree and generates tuples (event, element) in a
+    SAX-like fashion. ``event`` is any of 'start', 'end', 'start-ns',
+    'end-ns'.
+
+    For 'start' and 'end', ``element`` is the Element that the parser just
+    found opening or closing.  For 'start-ns', it is a tuple (prefix, URI) of
+    a new namespace declaration.  For 'end-ns', it is simply None.  Note that
+    all start and end events are guaranteed to be properly nested.
+
+    The keyword argument ``events`` specifies a sequence of event type names
+    that should be generated.  By default, only 'end' events will be
+    generated.
+
+    The additional ``tag`` argument restricts the 'start' and 'end' events to
+    those elements that match the given tag.  The ``tag`` argument can also be
+    a sequence of tags to allow matching more than one tag.  By default,
+    events are generated for all elements.  Note that the 'start-ns' and
+    'end-ns' events are not impacted by this restriction.
+
+    The other keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if validation or
+    attribute default values are requested.
+
+    Available boolean keyword arguments:
+     - attribute_defaults: read default attributes from DTD
+     - dtd_validation: validate (if DTD is available)
+     - load_dtd: use DTD for parsing
+     - no_network: prevent network access for related files
+     - remove_blank_text: discard blank text nodes
+     - remove_comments: discard comments
+     - remove_pis: discard processing instructions
+     - strip_cdata: replace CDATA sections by normal text content (default: True)
+     - compact: safe memory for short text content (default: True)
+     - resolve_entities: replace entities by their text value (default: True)
+     - huge_tree: disable security restrictions and support very deep trees
+                  and very long text content (only affects libxml2 2.7+)
+     - html: parse input as HTML (default: XML)
+     - recover: try hard to parse through broken input (default: True for HTML,
+                False otherwise)
+
+    Other keyword arguments:
+     - encoding: override the document encoding
+     - schema: an XMLSchema to validate against

+
+    The XML parser.
+
+    Parsers can be supplied as additional argument to various parse
+    functions of the lxml API.  A default parser is always available
+    and can be replaced by a call to the global function
+    'set_default_parser'.  New parsers can be created at any time
+    without a major run-time overhead.
+
+    The keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if DTD
+    validation or attribute default values are requested (unless you
+    additionally provide an XMLSchema from which the default
+    attributes can be read).
+
+    Available boolean keyword arguments:
+
+    - attribute_defaults - inject default attributes from DTD or XMLSchema
+    - dtd_validation     - validate against a DTD referenced by the document
+    - load_dtd           - use DTD for parsing
+    - no_network         - prevent network access for related files (default: True)
+    - ns_clean           - clean up redundant namespace declarations
+    - recover            - try hard to parse through broken XML
+    - remove_blank_text  - discard blank text nodes that appear ignorable
+    - remove_comments    - discard comments
+    - remove_pis         - discard processing instructions
+    - strip_cdata        - replace CDATA sections by normal text content (default: True)
+    - compact            - save memory for short text content (default: True)
+    - collect_ids        - use a hash table of XML IDs for fast access (default: True, always True with DTD validation)
+    - huge_tree          - disable security restrictions and support very deep trees
+                           and very long text content (only affects libxml2 2.7+)
+
+    Other keyword arguments:
+
+    - resolve_entities - replace entities by their text value: False for keeping the
+          entity references, True for resolving them, and 'internal' for resolving
+          internal definitions only (no external file/URL access).
+          The default used to be True and was changed to 'internal' in lxml 5.0.
+    - encoding - override the document encoding (note: libiconv encoding name)
+    - target   - a parser target object that will receive the parse events
+    - schema   - an XMLSchema to validate against
+
+    Note that you should avoid sharing parsers between threads.  While this is
+    not harmful, it is more efficient to use separate parsers.  This does not
+    apply to the default parser.
