<h3><abbr title="Document Object Model">DOM</abbr></h3>

<p>The current implementation assumes that there are following 
requirements:</p>
<ul>
<li>The document element (or root element) <em class=rfc2119>MUST</em>
be allowed to be a root element.  <span class=example>For example,
an <code>html</code> element in <code>http://www.w3.org/1999/xhtml</code>
namespace is allowed to be a root element by the HTML5
specification.</span></li>
</ul>
</div>

<div class=section id=html>
<h3><abbr title="Hypertext Markup Language">HTML</abbr></h3>

<p>HTML5 is partially implemented.</p>

<p>In addition, the current implementation assumes that there are following 
requirements:</p>
<ul>
<li>Any attribute in the HTML namespace which is not defined by the
HTML5 specification (including Web Forms 2.0 specification) 
<em class=rfc2119>MUST NOT</em> be used.</li>
<li>For an element in the HTML namespace, any attribute in the null namespace
(or per$B!>(Belement partition) <em class=rfc2119>MUST NOT</em> be used
unless it is allowed by the HTML5 specification (including Web Forms 2.0
specification).</li>
<li class=ed>@@ Forms elements: ...

<li>For the attribute not defined in HTML5, the following definitions are
applied.

  <div class="note memo">
  <p>These definitions are updated version of their original definitions
  in previous versions of HTML (i.e. HTML 2.x, HTML4, Web Forms 2.0,
  or early drafts of HTML5).
  </div>

  <p>For each row in the table below, if an attribute (i.e. an
  <code>Attr</code> node) met the following conditions, then the
  <code>value</code> attribute value of the node <em class=rfc2119>MUST</em>
  be valid with regard to the constraints shown in the <q>Value</q>
  cell of the row.  The conditions are:
    <ul>
    <li>There is an owner element (i.e. the <code>Element</code> node
    pointed by the <code>ownerElement</code> attribute of the 
    <code>Attr</code> node).
    <li>The <code>namespaceURI</code> attribute value of the owner element
    is <code>http://www.w3.org/1999/xhtml</code>.
    <li>The <code>manakaiLocalName</code> attribute value [@@ TODO: ref]
    of the owner element is equal to the value in the <q>Element</q> cell
    of the row.
    <li>The <code>namespaceURI</code> attribute value of the <code>Attr</code>
    node is <code>null</code>.

    <code>Attr</code> node is equal to the value in the <q>Attribute</q>

addition, the reference to the definition of the attribute is linked

2.x, DTD comment implies that this attribute applies to type=image.
In HTML 2.0, this attribute is only explained for type=image in the
prose.  --> Any of these attributes <em class=rfc2119>MUST NOT</em> be

<p id=cache-manifest>The 
<a href="http://www.whatwg.org/specs/web-apps/current-work/#manifests">cache
manifest syntax</a> is also supported.
</div>

<div class=section id=atom>
<h3>Atom</h3>

<p><a href="urn:ietf:rfc:4287">Atom 1.0</a> and 
<a href="urn:ietf:rfc:4685">Atom Threading 1.0</a> are supported.

<p>However, conformance to some <em class=rfc2119>SHOULD</em>-level
requirements, as well as some informational guidelines, are currently
not checked.  In addition, whether an email-address or a Base64
encoding is correct or not is not checked either.

<p>Use of XML digital signature and encryption is not supported.

<p>The current implementation assumes that there are following 
requirements:</p>
<ul>
<li>Elements and attributes in the Atom namespace, as well as attributes
in the null namespace for an element in the Atom namespace,
<em class=rfc2119>MUST NOT</em>
be used except for contexts where they are allowed by the Atom 
specification.</li>
<li>Inter-element whitespace [HTML5], processing instructions, and
comments <em class=rfc2119>MUST</em> be ignored for the purpose of 
conformance of the content of an element.
</ul>
</div>

<div class=section id=css>
<h3><abbr title="Cascading Style Sheets">CSS</abbr></h3>

<p>CSS @namespace and Selectors Level 3 are fully implemented.</p>

(<time datetime=2007-07-19>19 July 2007</time> Candidate Recommendation)</a>
is implemented.
<!-- @@ TODO: What is missing? -->

<p>Most of <a href="http://www.w3.org/TR/2008/WD-css3-color-20080721/">CSS 
Color Module Level 3 (<time datetime=2008-07-21>21 July 2008</time> Last
Call Working Draft)</a> is implemented.
<!-- @@ TODO: What is missing? -->

<p>Since the <abbr title="Cascading Style Sheets">CSS</abbr> 2.1
specification is sometimes ambigious or disagree with browsers,
our implementation is tend to copy what browsers do unless
there is strong resaon to do different thing.</p>

<p>In addition, the current implementation assumes that there are following 
requirements:</p>
<ul>
<li id=css-type-charset-param>The <code>charset</code> parameter of the media 
type <code>text/css</code> <em class=rfc2119>MUST</em> be treated as if it 
were an unknown parameter for the purpose of determining styling langauge for 
an <abbr>HTML</abbr> <code>style</code> element.</li>
<li id=css-style-content>Content of an <abbr>HTML</abbr> <code>style</code> 
element whose content is interpreted as a CSS style sheet 
<em class=rfc2119>MUST</em> consist of zero or more 
<a href="http://www.whatwg.org/specs/web-apps/current-work/#text-node">text nodes</a>.
Note that it may also contain zero or more comment and/or processing 
instruction nodes.</li>
</ul>

</div>

<div class=section id=regexp>
<h3>Regular expressions</h3>

<p>Regular expression defined in ECMAScript Third Edition Section
15.10.1 is implemented, with the addition of the support for obsolete
octal escape notation commonly supported by Web browsers.

<p>To identify ECMAScript regular expressions, the Internet Media Type
<a
href="http://suika.fam.cx/%7Ewakaba/wiki/sw/n/text+x-regexp-js"><code>text/x-regexp-js</code></a>
is used.
