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><h2 class="no-num no-toc" id="status-of-this-document">Status of This document</h2><p><em>This section describes the status of this document at the

mailing lists and take part in the discussions.</p><div id="multipage-common">

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><!-- UNDER NO CIRCUMSTANCES IS THE FOLLOWING PARAGRAPH TO BE REMOVED OR EDITED WITHOUT TALKING TO IAN FIRST -->
