With due respect: Normative guidance regarding values for alternative text is clearly the domain of WAI (specifically Web Content Accessibility Guidelines Working Group). Their charter states (in part): 4. Expanding techniques[*] for implementing the WCAG 2.0 in W3C and non-W3C technologies; 11. Coordinating with other Working Groups to address new accessibility issues from an authoring perspective; (with an emphasis on *authoring perspective*) - http://www.w3.org/WAI/GL/2010/06/charter - * HTML Techniques for WCAG 2.0 - http://www.w3.org/TR/2004/WD-WCAG20-HTML-TECHS-20041119/#images -------- A review of the HTML WG Charter (http://www.w3.org/2007/03/HTML-WG-charter.html) indicates this complete list of deliverables (by Charter): "...a single specification deliverable for the HTML Working Group, the HTML specification, a platform-neutral and device-independent design with the following items in scope: * A language evolved from HTML4 for describing the semantics of documents and applications on the World Wide Web. This will be a complete specification, not a delta specification. * An extensible, serialized form of such a language, using XML. * A serialized form of such a language using a defined, non-XML syntax compatible with the 'classic HTML' parsers of existing Web browsers. * Document Object Model (DOM) interfaces providing APIs for such a language. * Forms and common UI widgets such as progress bars, datagrids, menus, and other controls. * APIs for the manipulation of linked media. * Editing APIs and user-driven WYSIWYG editing features. It goes on to state however that: "The HTML Working Group will cooperate with the Web Accessibility Initiative to ensure that the deliverables will satisfy accessibility requirements. Coordination with WAI will be primarily conducted through the Protocol and Formats Working Group, but direct coordination with other WAI groups, such as Web Content Accessibility Guidelines Working Group and User Agent Accessibility Guidelines Working Group, will also be done when appropriate." Moreover, nowhere in the HTML WG Charter do I see providing (normative) Authoring Guidance as part of this WG's scope, outside of the creation of "HTML5: Techniques for providing useful text alternatives", the editor of this document currently being Stephen Faulkner. A reading of this Draft Techniques document confirms it is very much in sync with WCAG 2: it is an extension to the existing Techniques documents with a specific focus on textual alternatives. WCAG 2 is the normative W3C Recommendation (http://www.w3.org/TR/WCAG20/ - 11 December 2008) for ensuring accessibility of HTML and related web content. "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." I truly hope that it is not the intent of the Chairs and this Working Group to invoke a "willful violation" of WCAG 2, and so in principle I believe what Laura states is essentially correct: providing author guidance "...to address new (and one must presume existing) accessibility issues from an authoring perspective..." is indeed the domain of WAI/PFWG/WCAG. Can the Chairs confirm that they do not intend to willfully violate WCAG 2? JF
