<h2 class="no-num no-toc">Issues</h2>
<p>The use of the storage mutex to avoid race conditions is
currently considered by certain implementors to be too high a
performance burden, to the point where allowing data corruption is
considered preferable. Alternatives that do not require a
user-agent-wide per-origin script lock are eagerly sought after. If
reviewers have any suggestions, they are urged to send them to the
addresses given in the previous section.</p>
<p>More details regarding this issue are available in these
e-mails (as well as <a href="http://lists.whatwg.org/mmsearch.cgi/whatwg-whatwg.org?config=whatwg-whatwg.org&restrict=&exclude=&method=and&format=short&sort=revtime&words=storage+mutex">numerous others</a>):</p>

<h2>Conformance requirements</h2>
<p>All diagrams, examples, and notes in this specification are
non-normative, as are all sections explicitly marked non-normative.
Everything else in this specification is normative.</p>
<p>The key words "MUST", "MUST NOT", "REQUIRED", <!--"SHALL", "SHALL
NOT",--> "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
"OPTIONAL" in the normative parts of this document are to be
interpreted as described in RFC2119. For readability, these words do
not appear in all uppercase letters in this specification. <a
href="#refsRFC2119">[RFC2119]</a></p>
<p>Requirements phrased in the imperative as part of algorithms
(such as "strip any leading space characters" or "return false and
abort these steps") are to be interpreted with the meaning of the
key word ("must", "should", "may", etc) used in introducing the
algorithm.</p>
<p>Some conformance requirements are phrased as requirements on
attributes, methods or objects. Such requirements are to be
interpreted as requirements on user agents.</p>
<p>Conformance requirements phrased as algorithms or specific steps
may be implemented in any manner, so long as the end result is
equivalent. (In particular, the algorithms defined in this
specification are intended to be easy to follow, and not intended to
be performant.)</p>
<p>The only conformance class defined by this specification is user
agents.</p>
<p>User agents may impose implementation-specific limits on
otherwise unconstrained inputs, e.g. to prevent denial of service
attacks, to guard against running out of memory, or to work around
platform-specific limitations.</p>
<p>When support for a feature is disabled (e.g. as an emergency
measure to mitigate a security problem, or to aid in development, or
for performance reasons), user agents must act as if they had no
support for the feature whatsoever, and as if the feature was not
mentioned in this specification. For example, if a particular
feature is accessed via an attribute in a Web IDL interface, the
attribute itself would be omitted from the objects that implement
that interface — leaving the attribute on the object but
making it return null or throw an exception is insufficient.</p>
<h3>Dependencies</h3>
<p>This specification relies on several other underlying
specifications.</p>
<dl>
<dt>HTML</dt>
<dd>
<p>Many fundamental concepts from HTML are used by this
specification. <a href="#refsHTML">[HTML]</a></p>
</dd>
<dt>WebIDL</dt>
<dd>
<p>The IDL blocks in this specification use the semantics of the
WebIDL specification. <a href="#refsWEBIDL">[WEBIDL]</a></p>
</dd>
</dl>
<h2>Terminology</h2>
<p>The construction "a <code title="">Foo</code> object", where
<code title="">Foo</code> is actually an interface, is sometimes
used instead of the more accurate "an object implementing the
interface <code title="">Foo</code>".</p>
<p>The term DOM is used to refer to the API set made available to
scripts in Web applications, and does not necessarily imply the
existence of an actual <code>Document</code> object or of any other
<code>Node</code> objects as defined in the DOM Core
specifications. <a href="#refsDOMCORE">[DOMCORE]</a></p>
<p>An IDL attribute is said to be <em>getting</em> when its value is
being retrieved (e.g. by author script), and is said to be
<em>setting</em> when a new value is assigned to it.</p>

<h2 class="no-num no-toc">Abstract</h2>
<p>This specification defines the 5th major revision of the core
language of the World Wide Web: the Hypertext Markup Language
(HTML). In this version, new features are introduced to help Web
application authors, new elements are introduced based on research
into prevailing authoring practices, and special attention has been
given to defining clear conformance criteria for user agents in an
effort to improve interoperability.</p>

<p>The publication of this document by the W3C as a W3C Working
Draft does not imply that all of the participants in the W3C HTML
working group endorse the contents of the specification. Indeed, for
any section of the specification, one can usually find many members
of the working group or of the W3C as a whole who object strongly to
the current text, the existence of the section at all, or the idea
that the working group should even spend time discussing the concept
of that section.</p>

<h2 class="no-num no-toc">Abstract</h2>
<p>This specification defines the HTML microdata mechanism. This
mechanism allows machine-readable data to be embedded in HTML

<h2>Common infrastructure</h2>
<p>This specification is designed to be used with a <dfn>host

<ul class="brief">
<li>DOM <dfn>collections</dfn>
<li>The <dfn><code>HTMLCollection</code> interface</dfn>

<h3>Dependencies</h3>
<p>This specification depends on the Web IDL and HTML5
specifications. <a href="#refsWEBIDL">[WEBIDL]</a> <a
href="#refsHTML5">[HTML5]</a></p>
<h3>Terminology</h3>
<p>This specification relies heavily on the HTML5 specification to
define underlying terms.</p>
<p>HTML5 defines the concept of DOM <dfn>collections</dfn> and the
<dfn><code>HTMLCollection</code></dfn> interface, as well as the
concept of IDL attributes <dfn title="reflect">reflecting</dfn>
content attributes. It also defines <dfn>tree order</dfn> and the
concept of a node's <dfn>home subtree</dfn>.</p>
<p>HTML5 defines the terms <dfn>URL</dfn>, <dfn>valid URL</dfn>,
<dfn>absolute URL</dfn>, and <dfn>resolve a URL</dfn>.</p>
<p>HTML5 defines the terms <dfn>alphanumeric ASCII characters</dfn>,
<dfn>space characters</dfn> <dfn>split a string on spaces</dfn>,
<dfn>converted to ASCII uppercase</dfn>, and <dfn>prefix
match</dfn>.</p>
<p>HTML5 defines the meaning of the term <dfn>HTML elements</dfn>, as
well as all the elements referenced in this specification. It also
defines the <dfn><code>HTMLElement</code></dfn> and
<dfn><code>HTMLDocument</code></dfn> interfaces. It defines the
specific concept of <dfn>the <code>title</code> element</dfn> in the
context of an <code>HTMLDocument</code>. In the context of content
models it defines the terms <dfn>flow content</dfn> and
<dfn>phrasing content</dfn>. It also defines what an element's <dfn
title="concept-ID">ID</dfn> or <dfn>language</dfn> is in HTML.</p>
<p>HTML5 defines the set of <dfn>global attributes</dfn>, as well as
terms used in describing attributes and their processing, such as
the concept of a <dfn>boolean attribute</dfn>, of an <dfn>unordered
set of unique space-separated tokens</dfn>, of a <dfn>valid
non-negative integer</dfn>, of a <dfn
title="concept-date">date</dfn>, a <dfn
title="concept-time">time</dfn>, a <dfn
title="concept-datetime">global date and time</dfn>, a <dfn>valid
date string</dfn>, and a <dfn>valid global date and time
string</dfn>.</p>
<p>HTML5 defines what <dfn>the document's current address</dfn>
is.</p>
<p>Finally, HTML5 also defines the concepts of <dfn>drag-and-drop
initialization steps</dfn> and of the <dfn>list of dragged
nodes</dfn>, which come up in the context of drag-and-drop
interfaces.</p>
