Aaron, This is an important issue. UAWG was already planning on reviewing the document when it is complete. UAWG is have a meeting today and will discuss the remaining items. I think there will need to be some coordination as UAAG is in transition from version 1.0 to 2.0. We need to ensure that the guidelines and the implementation guide are in harmony. One of the area that is under review is Principal 2 Facilitate access by assistive technologies - http://www.w3.org/TR/2008/WD-UAAG20-20080312/#principle-AT-access which has guideline that cover ARIA. It would be useful if you or some other developer of the guide could attend a future UAWG call before the end of April to discuss the guide. I would be happy to coordinate with you. UAWG meets every Thursday at 2 pm Eastern time.

To web application developers and assistive technology vendors this come down to how ARIA is mapped to platform accessibility APIs by the browser. Customer demand for accessible rich internet applications has brought the major browser manufacturers, Mozilla, Opera, Microsoft, and Apple together to define how we will map WAI-ARIA to platform accessibility API. To get the effort jump-started I've created a first WAI-ARIA User agent implementers guide (http://developer.mozilla.org/en/docs/ARIA_User_Agent_Implementors_Guide) which is based on the Firefox Accessibility API mapping. This document is a starting point for us browser manufacturers and it is still undergoing major revisions. Many of these revisions have to do with varying API support. Ultimately, the document should belong to the UAWG working group, however after lengthy discussion among us we would ask that you allow us to produce a first draft before turning it over to UAWG for participation. We feel this could be done by early to mid May. In creating the first draft we will: - Work to synchronize accessibility API mapping wherever possible - Make use of the latest platform accessibility APIs to expose the richness of today's web. This was not possible even two years ago. - Ensure we explain how ARIA relates back to HTML and this will be in line with the HTML WG's agenda to clarify HTML. I would even go further and say that once these mappings are ready, that something like the "acid tests" should be implemented for each platform, to keep browser implementations of a11y in sync. Getting the API mappings right is the hardest part of getting accessibility right in browsers, and the most useful information for us. To me, this is what UAWG should be working on, if the W3C permits you to deal directly with platform-specific technologies. IMO it should, because in the end that will produce the biggest benefits for a11y. We would like to ask that the UAWG take on: 1) Review of http://developer.mozilla.org/en/docs/ARIA_User_Agent_Implementors_Guide 2) Development of a similar guide for HTML 3) Development of a11y API acid tests to check for errors Is this acceptable to UAWG?
