Call for Review: HTML Image Description Extension (longdesc)

Dear WAI Interest Group Participants,

The W3C HTML Working Group today published the First Public Working Draft of:
     HTML Image Description Extension

This specification ("HTML-longdesc") enables web authors to provide longer text descriptions for complex images. It defines the "longdesc" attribute to link descriptions with images in HTML5 content.

HTML-longdesc is an extension specification that is part of the HTML5 family of specifications [1], which enables it to evolve independently and be finalized more rapidly. HTML-longdesc is part of W3C's work to ensure that the Open Web Platform [2] is accessible to people with disabilities [3].

Based on this publication, the following changes will be implemented in the coming weeks:
* W3C validator [4] will validate longdesc as conforming HTML5.
* longdesc will be removed from the HTML obsolete features list.

Comments: Please send any comments on this Draft to the publicly archived HTML Accessibility Task Force mailing list:
     by 10 April 2013

Working Groups: HTML-longdesc was developed by the HTML Accessibility Task Force under the WAI Protocols and Formats Working Group (PFWG) and the HTML Working Group (HTML WG). [5]
