An attribute to support the role classification of elements

Abstract

The Role Attribute defined in this specification allows the author to annotate markup languages with machine-extractable semantic information about the purpose of an element. Use cases include accessibility, device adaptation, server-side processing, and complex data description. This attribute can be integrated into any markup language. In particular, schema implementations are provided to facilitate with languages based upon XHTML Modularization [XHTML-MODULARIZATION11-2e].
The role attribute is necessary to support Accessible Rich Internet Applications (WAI-ARIA) [WAI-ARIA] to define roles in XML-based languages, when the languages do not define their own role attribute. Although this is the reason the Role Attribute is published by the Protocols and Formats Working Group, the attribute has more general use cases as well.

Status of This Document

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
This is the Role Attribute W3C Recommendation by the Protocols & Formats Working Group of the Web Accessibility Initiative. This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited 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.
As a finalized document, this version of the Role Attribute is not likely to undergo further changes. The Protocols and Formats Working Group expects that any further enhancements to the Role Attribute would take place in a future version of Accessible Rich Internet Applications (WAI-ARIA), instead of in a future version of this specification. The Working Group does not plan to make formal responses to comments on the Role Attribute Recommendation, but will consider input for errata or other future work. Start with the instructions for commenting page to submit comments (preferred), or send email to public-pfwg-comments@w3.org (comment archive). A history of changes to Role Attribute 1.0 is available.
