+Change Log
+----------
+
+0.9999
+~~~~~~
+
+Released on XXX, 2014
+
+* XXX
+
+
+0.999
+~~~~~
+
+Released on December 23, 2013
+
+* Fix #127: add work-around for CPython issue #20007: .read(0) on
+  http.client.HTTPResponse drops the rest of the content.
+
+* Fix #115: lxml treewalker can now deal with fragments containing, at
+  their root level, text nodes with non-ASCII characters on Python 2.
+
+
+0.99
+~~~~
+
+Released on September 10, 2013
+
+* No library changes from 1.0b3; released as 0.99 as pip has changed
+  behaviour from 1.4 to avoid installing pre-release versions per
+  PEP 440.
+
+
+1.0b3
+~~~~~
+
+Released on July 24, 2013
+
+* Removed ``RecursiveTreeWalker`` from ``treewalkers._base``. Any
+  implementation using it should be moved to
+  ``NonRecursiveTreeWalker``, as everything bundled with html5lib has
+  for years.
+
+* Fix #67 so that ``BufferedStream`` to correctly returns a bytes
+  object, thereby fixing any case where html5lib is passed a
+  non-seekable RawIOBase-like object.
+
+
+1.0b2
+~~~~~
+
+Released on June 27, 2013
+
+* Removed reordering of attributes within the serializer. There is now
+  an ``alphabetical_attributes`` option which preserves the previous
+  behaviour through a new filter. This allows attribute order to be
+  preserved through html5lib if the tree builder preserves order.
+
+* Removed ``dom2sax`` from DOM treebuilders. It has been replaced by
+  ``treeadapters.sax.to_sax`` which is generic and supports any
+  treewalker; it also resolves all known bugs with ``dom2sax``.
+
+* Fix treewalker assertions on hitting bytes strings on
+  Python 2. Previous to 1.0b1, treewalkers coped with mixed
+  bytes/unicode data on Python 2; this reintroduces this prior
+  behaviour on Python 2. Behaviour is unchanged on Python 3.
+
+
+1.0b1
+~~~~~
+
+Released on May 17, 2013
+
+* Implementation updated to implement the `HTML specification
+  <http://www.whatwg.org/specs/web-apps/current-work/>`_ as of 5th May
+  2013 (`SVN <http://svn.whatwg.org/webapps/>`_ revision r7867).
+
+* Python 3.2+ supported in a single codebase using the ``six`` library.
+
+* Removed support for Python 2.5 and older.
+
+* Removed the deprecated Beautiful Soup 3 treebuilder.
+  ``beautifulsoup4`` can use ``html5lib`` as a parser instead. Note that
+  since it doesn't support namespaces, foreign content like SVG and
+  MathML is parsed incorrectly.
+
+* Removed ``simpletree`` from the package. The default tree builder is
+  now ``etree`` (using the ``xml.etree.cElementTree`` implementation if
+  available, and ``xml.etree.ElementTree`` otherwise).
+
+* Removed the ``XHTMLSerializer`` as it never actually guaranteed its
+  output was well-formed XML, and hence provided little of use.
+
+* Removed default DOM treebuilder, so ``html5lib.treebuilders.dom`` is no
+  longer supported. ``html5lib.treebuilders.getTreeBuilder("dom")`` will
+  return the default DOM treebuilder, which uses ``xml.dom.minidom``.
+
+* Optional heuristic character encoding detection now based on
+  ``charade`` for Python 2.6 - 3.3 compatibility.
+
+* Optional ``Genshi`` treewalker support fixed.
+
+* Many bugfixes, including:
+
+  * #33: null in attribute value breaks XML AttValue;
+
+  * #4: nested, indirect descendant, <button> causes infinite loop;
+
+  * `Google Code 215
+    <http://code.google.com/p/html5lib/issues/detail?id=215>`_: Properly
+    detect seekable streams;
+
+  * `Google Code 206
+    <http://code.google.com/p/html5lib/issues/detail?id=206>`_: add
+    support for <video preload=...>, <audio preload=...>;
+
+  * `Google Code 205
+    <http://code.google.com/p/html5lib/issues/detail?id=205>`_: add
+    support for <video poster=...>;
+
+  * `Google Code 202
+    <http://code.google.com/p/html5lib/issues/detail?id=202>`_: Unicode
+    file breaks InputStream.
+
+* Source code is now mostly PEP 8 compliant.
+
+* Test harness has been improved and now depends on ``nose``.
+
+* Documentation updated and moved to http://html5lib.readthedocs.org/.

+Contributing
+============
+
+Pull requests are more than welcome — both to the library and to the
+documentation. Some useful information:
+
+- We aim to follow PEP 8 in the library, but ignoring the
+  79-character-per-line limit, instead following a soft limit of 99,
+  but allowing lines over this where it is the readable thing to do.
+
+- We aim to follow PEP 257 for all docstrings, and make them properly
+  parseable by Sphinx while generating API documentation.
+
+- We keep ``pyflakes`` reporting no errors or warnings at all times.
+
+- We keep the master branch passing all tests at all times on all
+  supported versions.
+
+`Travis CI <https://travis-ci.org/html5lib/html5lib-python/>`_ is run
+against all pull requests and should enforce all of the above.
+
+We use `Opera Critic <https://critic.hoppipolla.co.uk/>`_ as an external
+code-review tool, which uses your GitHub login to authenticate.  You'll
+get email notifications for issues raised in the review.
+
+
+Patch submission guidelines

+  multiple fixes/features in the same pull request. If you find an
+  unrelated bug, create a distinct branch and submit a separate pull
+  request for the bugfix. This makes life much easier for maintainers
+  and will speed up merging your patches.
+
+- **Write a test** whenever possible. Following existing tests is often
+  easiest, and a good way to tell whether the feature you're modifying
+  is easily testable.
+
+- **Make sure documentation is updated.** Keep docstrings current, and
+  if necessary, update the Sphinx documentation in ``doc/``.
+
+- **Add a changelog entry** at the top of ``CHANGES.rst`` following
+  existing entries' styles.
+
+- **Run tests with tox** if possible, to make sure your changes are
+  compatible with all supported Python versions.
+
+- **Squash commits** before submitting the pull request so that a single
+  commit contains the entire change, and only that change (see the first
+  bullet).
+
+- **Don't rebase after creating the pull request.** Merge with upstream,
+  if necessary, and use ``git commit --fixup`` for fixing issues raised
+  in a Critic review or by a failing Travis build. The reviewer will
+  squash and rebase your pull request while accepting it. Even though
+  GitHub won't recognize the pull request as accepted, the squashed
+  commits will properly specify you as the author.
+
+- **Attribute yourself** in ``AUTHORS.rst``.

+html5lib
+========
+
+.. image:: https://travis-ci.org/html5lib/html5lib-python.png?branch=master
+  :target: https://travis-ci.org/html5lib/html5lib-python
+
+html5lib is a pure-python library for parsing HTML. It is designed to
+conform to the WHATWG HTML specification, as is implemented by all major
+web browsers.
+
+
+Usage
+-----
+
+Simple usage follows this pattern:
+
+.. code-block:: python
+
+  import html5lib
+  with open("mydocument.html", "rb") as f:
+      document = html5lib.parse(f)
+
+or:
+
+.. code-block:: python
+
+  import html5lib
+  document = html5lib.parse("<p>Hello World!")
+
+By default, the ``document`` will be an ``xml.etree`` element instance.
+Whenever possible, html5lib chooses the accelerated ``ElementTree``
+implementation (i.e. ``xml.etree.cElementTree`` on Python 2.x).
+
+Two other tree types are supported: ``xml.dom.minidom`` and
+``lxml.etree``. To use an alternative format, specify the name of
+a treebuilder:
+
+.. code-block:: python
+
+  import html5lib
+  with open("mydocument.html", "rb") as f:
+      lxml_etree_document = html5lib.parse(f, treebuilder="lxml")
+
+When using with ``urllib2`` (Python 2), the charset from HTTP should be
+pass into html5lib as follows:
+
+.. code-block:: python
+
+  from contextlib import closing
+  from urllib2 import urlopen
+  import html5lib
+
+  with closing(urlopen("http://example.com/")) as f:
+      document = html5lib.parse(f, encoding=f.info().getparam("charset"))
+
+When using with ``urllib.request`` (Python 3), the charset from HTTP
+should be pass into html5lib as follows:
+
+.. code-block:: python
+
+  from urllib.request import urlopen
+  import html5lib
+
+  with urlopen("http://example.com/") as f:
+      document = html5lib.parse(f, encoding=f.info().get_content_charset())
+
+To have more control over the parser, create a parser object explicitly.
+For instance, to make the parser raise exceptions on parse errors, use:
+
+.. code-block:: python
+
+  import html5lib
+  with open("mydocument.html", "rb") as f:
+      parser = html5lib.HTMLParser(strict=True)
+      document = parser.parse(f)
+
+When you're instantiating parser objects explicitly, pass a treebuilder
+class as the ``tree`` keyword argument to use an alternative document
+format:
+
+.. code-block:: python
+
+  import html5lib
+  parser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("dom"))
+  minidom_document = parser.parse("<p>Hello World!")
+
+More documentation is available at http://html5lib.readthedocs.org/.
+
+
+Installation
+------------
+
+html5lib works on CPython 2.6+, CPython 3.2+ and PyPy.  To install it,
+use:
+
+.. code-block:: bash
+
+    $ pip install html5lib
+
+
+Optional Dependencies
+---------------------
+
+The following third-party libraries may be used for additional
+functionality:
+
+- ``datrie`` can be used to improve parsing performance (though in
+  almost all cases the improvement is marginal);
+
+- ``lxml`` is supported as a tree format (for both building and
+  walking) under CPython (but *not* PyPy where it is known to cause
+  segfaults);
+
+- ``genshi`` has a treewalker (but not builder); and
+
+- ``charade`` can be used as a fallback when character encoding cannot
+  be determined; ``chardet``, from which it was forked, can also be used
+  on Python 2.
+
+- ``ordereddict`` can be used under Python 2.6
+  (``collections.OrderedDict`` is used instead on later versions) to
+  serialize attributes in alphabetical order.
+
+
+Bugs
+----
+
+Please report any bugs on the `issue tracker
+<https://github.com/html5lib/html5lib-python/issues>`_.
+
+
+Tests
+-----
+
+Unit tests require the ``nose`` library and can be run using the
+``nosetests`` command in the root directory; ``ordereddict`` is
+required under Python 2.6. All should pass.
+
+Test data are contained in a separate `html5lib-tests
+<https://github.com/html5lib/html5lib-tests>`_ repository and included
+as a submodule, thus for git checkouts they must be initialized::
+
+  $ git submodule init
+  $ git submodule update
+
+If you have all compatible Python implementations available on your
+system, you can run tests on all of them using the ``tox`` utility,
+which can be found on PyPI.
+
+
+Questions?
+----------
+
+There's a mailing list available for support on Google Groups,
+`html5lib-discuss <http://groups.google.com/group/html5lib-discuss>`_,
+though you may get a quicker response asking on IRC in `#whatwg on
+irc.freenode.net <http://wiki.whatwg.org/wiki/IRC>`_.

+The moving parts
+================
+
+html5lib consists of a number of components, which are responsible for
+handling its features.
+
+
+Tree builders
+-------------
+
+The parser reads HTML by tokenizing the content and building a tree that
+the user can later access. There are three main types of trees that
+html5lib can build:
+
+* ``etree`` - this is the default; builds a tree based on ``xml.etree``,
+  which can be found in the standard library. Whenever possible, the
+  accelerated ``ElementTree`` implementation (i.e.
+  ``xml.etree.cElementTree`` on Python 2.x) is used.
+
+* ``dom`` - builds a tree based on ``xml.dom.minidom``.
+
+* ``lxml.etree`` - uses lxml's implementation of the ``ElementTree``
+  API.  The performance gains are relatively small compared to using the
+  accelerated ``ElementTree`` module.
+
+You can specify the builder by name when using the shorthand API:
+
+.. code-block:: python
+
+  import html5lib
+  with open("mydocument.html", "rb") as f:
+      lxml_etree_document = html5lib.parse(f, treebuilder="lxml")
+
+When instantiating a parser object, you have to pass a tree builder
+class in the ``tree`` keyword attribute:
+
+.. code-block:: python
+
+  import html5lib
+  parser = html5lib.HTMLParser(tree=SomeTreeBuilder)
+  document = parser.parse("<p>Hello World!")
+
+To get a builder class by name, use the ``getTreeBuilder`` function:
+
+.. code-block:: python
+
+  import html5lib
+  parser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("dom"))
+  minidom_document = parser.parse("<p>Hello World!")
+
+The implementation of builders can be found in `html5lib/treebuilders/
+<https://github.com/html5lib/html5lib-python/tree/master/html5lib/treebuilders>`_.
+
+
+Tree walkers
+------------
+
+Once a tree is ready, you can work on it either manually, or using
+a tree walker, which provides a streaming view of the tree. html5lib
+provides walkers for all three supported types of trees (``etree``,
+``dom`` and ``lxml``).
+
+The implementation of walkers can be found in `html5lib/treewalkers/
+<https://github.com/html5lib/html5lib-python/tree/master/html5lib/treewalkers>`_.
+
+Walkers make consuming HTML easier. html5lib uses them to provide you
+with has a couple of handy tools.
+
+
+HTMLSerializer
+~~~~~~~~~~~~~~
+
+The serializer lets you write HTML back as a stream of bytes.
+
+.. code-block:: pycon
+
+  >>> import html5lib
+  >>> element = html5lib.parse('<p xml:lang="pl">Witam wszystkich')
+  >>> walker = html5lib.getTreeWalker("etree")
+  >>> stream = walker(element)
+  >>> s = html5lib.serializer.HTMLSerializer()
+  >>> output = s.serialize(stream)
+  >>> for item in output:
+  ...   print("%r" % item)
+  '<p'
+  ' '
+  'xml:lang'
+  '='
+  'pl'
+  '>'
+  'Witam wszystkich'
+
+You can customize the serializer behaviour in a variety of ways, consult
+the :class:`~html5lib.serializer.htmlserializer.HTMLSerializer`
+documentation.
+
+
+Filters
+~~~~~~~
+
+You can alter the stream content with filters provided by html5lib:
+
+* :class:`alphabeticalattributes.Filter
+  <html5lib.filters.alphabeticalattributes.Filter>` sorts attributes on
+  tags to be in alphabetical order
+
+* :class:`inject_meta_charset.Filter
+  <html5lib.filters.inject_meta_charset.Filter>` sets a user-specified
+  encoding in the correct ``<meta>`` tag in the ``<head>`` section of
+  the document
+
+* :class:`lint.Filter <html5lib.filters.lint.Filter>` raises
+  ``LintError`` exceptions on invalid tag and attribute names, invalid
+  PCDATA, etc.
+
+* :class:`optionaltags.Filter <html5lib.filters.optionaltags.Filter>`
+  removes tags from the stream which are not necessary to produce valid
+  HTML
+
+* :class:`sanitizer.Filter <html5lib.filters.sanitizer.Filter>` removes
+  unsafe markup and CSS. Elements that are known to be safe are passed
+  through and the rest is converted to visible text. The default
+  configuration of the sanitizer follows the `WHATWG Sanitization Rules
+  <http://wiki.whatwg.org/wiki/Sanitization_rules>`_.
+
+* :class:`whitespace.Filter <html5lib.filters.whitespace.Filter>`
+  collapses all whitespace characters to single spaces unless they're in
+  ``<pre/>`` or ``textarea`` tags.
+
+To use a filter, simply wrap it around a stream:
+
+.. code-block:: python
+
+  >>> import html5lib
+  >>> from html5lib.filters import sanitizer
+  >>> dom = html5lib.parse("<p><script>alert('Boo!')", treebuilder="dom")
+  >>> walker = html5lib.getTreeWalker("dom")
+  >>> stream = walker(dom)
+  >>> sane_stream = sanitizer.Filter(stream) clean_stream = sanitizer.Filter(stream)
+
+
+Tree adapters
+-------------
+
+Used to translate one type of tree to another. More documentation
+pending, sorry.
+
+
+Encoding discovery
+------------------
+
+Parsed trees are always Unicode. However a large variety of input
+encodings are supported. The encoding of the document is determined in
+the following way:
+
+* The encoding may be explicitly specified by passing the name of the
+  encoding as the encoding parameter to the
+  :meth:`~html5lib.html5parser.HTMLParser.parse` method on
+  ``HTMLParser`` objects.
+
+* If no encoding is specified, the parser will attempt to detect the
+  encoding from a ``<meta>``  element in the first 512 bytes of the
+  document (this is only a partial implementation of the current HTML
+  5 specification).
+
+* If no encoding can be found and the chardet library is available, an
+  attempt will be made to sniff the encoding from the byte pattern.
+
+* If all else fails, the default encoding will be used. This is usually
+  `Windows-1252 <http://en.wikipedia.org/wiki/Windows-1252>`_, which is
+  a common fallback used by Web browsers.
+
+
+Tokenizers
+----------
+
+The part of the parser responsible for translating a raw input stream
+into meaningful tokens is the tokenizer. Currently html5lib provides
+two.
+
+To set up a tokenizer, simply pass it when instantiating
+a :class:`~html5lib.html5parser.HTMLParser`:
+
+.. code-block:: python
+
+  import html5lib
+  from html5lib import sanitizer
+
+  p = html5lib.HTMLParser(tokenizer=sanitizer.HTMLSanitizer)
+  p.parse("<p>Surprise!<script>alert('Boo!');</script>")
+
+HTMLTokenizer
+~~~~~~~~~~~~~
+
+This is the default tokenizer, the heart of html5lib. The implementation
+can be found in `html5lib/tokenizer.py
+<https://github.com/html5lib/html5lib-python/blob/master/html5lib/tokenizer.py>`_.
+
+HTMLSanitizer
+~~~~~~~~~~~~~
+
+This is a tokenizer that removes unsafe markup and CSS styles from the
+input. Elements that are known to be safe are passed through and the
+rest is converted to visible text. The default configuration of the
+sanitizer follows the `WHATWG Sanitization Rules
+<http://wiki.whatwg.org/wiki/Sanitization_rules>`_.
+
+The implementation can be found in `html5lib/sanitizer.py
+<https://github.com/html5lib/html5lib-python/blob/master/html5lib/sanitizer.py>`_.

+Tokenizer tests
+===============
+
+The test format is [JSON](http://www.json.org/). This has the advantage
+that the syntax allows backward-compatible extensions to the tests and
+the disadvantage that it is relatively verbose.
+
+Basic Structure
+---------------
+
+    {"tests": [
+        {"description": "Test description",
+        "input": "input_string",
+        "output": [expected_output_tokens],
+        "initialStates": [initial_states],
+        "lastStartTag": last_start_tag,
+        "ignoreErrorOrder": ignore_error_order
+        }
+    ]}
+
+Multiple tests per file are allowed simply by adding more objects to the
+"tests" list.
+
+`description`, `input` and `output` are always present. The other values
+are optional.
+
+### Test set-up
+
+`test.input` is a string containing the characters to pass to the
+tokenizer. Specifically, it represents the characters of the **input
+stream**, and so implementations are expected to perform the processing
+described in the spec's **Preprocessing the input stream** section
+before feeding the result to the tokenizer.
+
+If `test.doubleEscaped` is present and `true`, then `test.input` is not
+quite as described above. Instead, it must first be subjected to another
+round of unescaping (i.e., in addition to any unescaping involved in the
+JSON import), and the result of *that* represents the characters of the
+input stream. Currently, the only unescaping required by this option is
+to convert each sequence of the form \\uHHHH (where H is a hex digit)
+into the corresponding Unicode code point. (Note that this option also
+affects the interpretation of `test.output`.)
+
+`test.initialStates` is a list of strings, each being the name of a
+tokenizer state. The test should be run once for each string, using it
+to set the tokenizer's initial state for that run. If
+`test.initialStates` is omitted, it defaults to `["data state"]`.
+
+`test.lastStartTag` is a lowercase string that should be used as "the
+tag name of the last start tag to have been emitted from this
+tokenizer", referenced in the spec's definition of **appropriate end tag
+token**. If it is omitted, it is treated as if "no start tag has been
+emitted from this tokenizer".
+
+### Test results
+
+`test.output` is a list of tokens, ordered with the first produced by
+the tokenizer the first (leftmost) in the list. The list must mach the
+**complete** list of tokens that the tokenizer should produce. Valid
+tokens are:
+
+    ["DOCTYPE", name, public_id, system_id, correctness]
+    ["StartTag", name, {attributes}*, true*]
+    ["StartTag", name, {attributes}]
+    ["EndTag", name]
+    ["Comment", data]
+    ["Character", data]
+    "ParseError"
+
+`public_id` and `system_id` are either strings or `null`. `correctness`
+is either `true` or `false`; `true` corresponds to the force-quirks flag
+being false, and vice-versa.
+
+When the self-closing flag is set, the `StartTag` array has `true` as
+its fourth entry. When the flag is not set, the array has only three
+entries for backwards compatibility.
+
+All adjacent character tokens are coalesced into a single
+`["Character", data]` token.
+
+If `test.doubleEscaped` is present and `true`, then every string within
+`test.output` must be further unescaped (as described above) before
+comparing with the tokenizer's output.
+
+`test.ignoreErrorOrder` is a boolean value indicating that the order of
+`ParseError` tokens relative to other tokens in the output stream is
+unimportant, and implementations should ignore such differences between
+their output and `expected_output_tokens`. (This is used for errors
+emitted by the input stream preprocessing stage, since it is useful to
+test that code but it is undefined when the errors occur). If it is
+omitted, it defaults to `false`.
+
+xmlViolation tests
+------------------
+
+`tokenizer/xmlViolation.test` differs from the above in a couple of
+ways:
+
+-   The name of the single member of the top-level JSON object is
+    "xmlViolationTests" instead of "tests".
+-   Each test's expected output assumes that implementation is applying
+    the tweaks given in the spec's "Coercing an HTML DOM into an
+    infoset" section.

+Tree Construction Tests
+=======================
+
+Each file containing tree construction tests consists of any number of
+tests separated by two newlines (LF) and a single newline before the end
+of the file. For instance:
+
+    [TEST]LF
+    LF
+    [TEST]LF
+    LF
+    [TEST]LF
+
+Where [TEST] is the following format:
+
+Each test must begin with a string "\#data" followed by a newline (LF).
+All subsequent lines until a line that says "\#errors" are the test data
+and must be passed to the system being tested unchanged, except with the
+final newline (on the last line) removed.
+
+Then there must be a line that says "\#errors". It must be followed by
+one line per parse error that a conformant checker would return. It
+doesn't matter what those lines are, although they can't be
+"\#document-fragment", "\#document", "\#script-off", "\#script-on", or
+empty, the only thing that matters is that there be the right number
+of parse errors.
+
+Then there \*may\* be a line that says "\#document-fragment", which must
+be followed by a newline (LF), followed by a string of characters that
+indicates the context element, followed by a newline (LF). If this line
+is present the "\#data" must be parsed using the HTML fragment parsing
+algorithm with the context element as context.
+
+Then there \*may\* be a line that says "\#script-off" or
+"\#script-in". If a line that says "\#script-off" is present, the
+parser must set the scripting flag to disabled. If a line that says
+"\#script-on" is present, it must set it to enabled. Otherwise, the
+test should be run in both modes.
+
+Then there must be a line that says "\#document", which must be followed
+by a dump of the tree of the parsed DOM. Each node must be represented
+by a single line. Each line must start with "| ", followed by two spaces
+per parent node that the node has before the root document node.
+
+-   Element nodes must be represented by a "`<`" then the *tag name
+    string* "`>`", and all the attributes must be given, sorted
+    lexicographically by UTF-16 code unit according to their *attribute
+    name string*, on subsequent lines, as if they were children of the
+    element node.
+-   Attribute nodes must have the *attribute name string*, then an "="
+    sign, then the attribute value in double quotes (").
+-   Text nodes must be the string, in double quotes. Newlines aren't
+    escaped.
+-   Comments must be "`<`" then "`!-- `" then the data then "` -->`".
+-   DOCTYPEs must be "`<!DOCTYPE `" then the name then if either of the
+    system id or public id is non-empty a space, public id in
+    double-quotes, another space an the system id in double-quotes, and
+    then in any case "`>`".
+-   Processing instructions must be "`<?`", then the target, then a
+    space, then the data and then "`>`". (The HTML parser cannot emit
+    processing instructions, but scripts can, and the WebVTT to DOM
+    rules can emit them.)
+-   Template contents are represented by the string "content" with the
+    children below it.
+
+The *tag name string* is the local name prefixed by a namespace
+designator. For the HTML namespace, the namespace designator is the
+empty string, i.e. there's no prefix. For the SVG namespace, the
+namespace designator is "svg ". For the MathML namespace, the namespace
+designator is "math ".
+
+The *attribute name string* is the local name prefixed by a namespace
+designator. For no namespace, the namespace designator is the empty
+string, i.e. there's no prefix. For the XLink namespace, the namespace
+designator is "xlink ". For the XML namespace, the namespace designator
+is "xml ". For the XMLNS namespace, the namespace designator is "xmlns
+". Note the difference between "xlink:href" which is an attribute in no
+namespace with the local name "xlink:href" and "xlink href" which is an
+attribute in the xlink namespace with the local name "href".
+
+If there is also a "\#document-fragment" the bit following "\#document"
+must be a representation of the HTML fragment serialization for the
+context element given by "\#document-fragment".
+
+For example:
+
+    #data
+    <p>One<p>Two
+    #errors
+    3: Missing document type declaration
+    #document
+    | <html>

+    |     <p>
+    |       "One"
+    |     <p>
+    |       "Two"

+"""A collection of modules for building different kinds of tree from

+
+To create a treebuilder for a new type of tree, you need to do
+implement several things:
+
+1) A set of classes for various types of elements: Document, Doctype,
+Comment, Element. These must implement the interface of
+_base.treebuilders.Node (although comment nodes have a different
+signature for their constructor, see treebuilders.etree.Comment)
+Textual content may also be implemented as another node type, or not, as
+your tree implementation requires.
+
+2) A treebuilder object (called TreeBuilder by convention) that
+inherits from treebuilders._base.TreeBuilder. This has 4 required attributes:
+documentClass - the class to use for the bottommost node of a document
+elementClass - the class to use for HTML Elements
+commentClass - the class to use for comments
+doctypeClass - the class to use for doctypes
+It also has one required method:
+getDocument - Returns the root node of the complete document tree
+
+3) If you wish to run the unit tests, you must also create a
+testSerializer method on your treebuilder which accepts a node and
+returns a string containing Node and its children serialized according
+to the format used in the unittests

+"""Module for supporting the lxml.etree library. The idea here is to use as much
+of the native library as possible, without using fragile hacks like custom element
+names that break between releases. The downside of this is that we cannot represent
+all possible trees; specifically the following are known to cause problems:
+
+Text or comments as siblings of the root element
+Docypes with no name
+
+When any of these things occur, we emit a DataLossWarning
