<h2><a name="abstract">Abstract</a></h2>
<p>This document specifies the second version of the Synchronized Multimedia
Integration Language (SMIL, pronounced "smile"). SMIL 2.1 has the following
design goals:</p>
<ul>
<li>Define an XML-based language that allows authors to write interactive
multimedia presentations. Using SMIL, an author can describe the temporal
behaviour of a multimedia presentation, associate hyperlinks with media
objects and describe the layout of the presentation on a screen.</li>
<li>Allow reusing of SMIL syntax and semantics in other XML-based
languages, in particular those who need to represent timing and
synchronization. For example, SMIL components are used for integrating
timing into XHTML <span class="normref"><a href="refs.html#ref-XHTML10" rel="biblioentry" class="noxref"><span class="inforef">[XHTML10]</span></a></span> and into SVG
<span class="normref"><a href="refs.html#ref-SVG" rel="biblioentry" class="noxref"><span class="inforef">[SVG]</span></a></span>.</li>
<li>Extend the functionalities contained in the SMIL 2.0 <a href="refs.html#ref-SMIL20" rel="biblioentry" class="noxref"><span class="normref">[SMIL20]</span></a> into
new or revised SMIL 2.1 modules.</li>
<li>Define new SMIL 2.1 Mobile Profiles incorporating features useful
within the mobile industry.</li>
</ul>

of the W3C. It has been reviewed by W3C Members and other interested parties
and has been endorsed by the Director as a W3C Recommendation. It is a stable
document and may be used as reference material or cited as a normative
reference from another document. W3C's role in making the Recommendation is
to draw attention to the specification and to promote its widespread
deployment. This enhances the functionality and interoperability of the
Web.</p>
<p>This SMIL 2.1 edition is a <em>new</em> version, it extends the
functionalities contained in SMIL 2.0 <a href="refs.html#ref-SMIL20" rel="biblioentry" class="noxref"><span class="normref">[SMIL20]</span></a>, incorporating new features
useful within the mobile industry.<br>
This SMIL 2.1 W3C Recommendation supersedes the <a

report</a> are publicly released and are intended solely to be used as proof
of SMIL 2.1 implementability. It is only a snapshot of the actual
implementation behaviors at one moment of time, as these implementations may
not be immediately available to the public. The interoperability data is not
intended to be used for assessing or grading the performance of any
