Dear WAI Interest Group Participants,
The W3C HTML Working Group today published the First Public Working Draft of:
HTML Image Description Extension
http://www.w3.org/TR/html-longdesc
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:
[email protected]
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]
