Abstract

   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.

   This document was published by the [46]HTML Working Group as a
   Candidate Recommendation. This document is intended to become a
   W3C Recommendation. W3C publishes a Candidate Recommendation to
   indicate that the document is believed to be stable and to

   Work on this specification is also done at the [47]WHATWG. The
   W3C HTML working group actively pursues convergence with the
   WHATWG, as required by the [48]W3C HTML working group charter.
   There are various ways to follow this work at the WHATWG:
     * Commit-Watchers mailing list (complete source diffs):

   The following features are at risk and may be removed due to
   lack of implementation.
     * [51]<hgroup>
