Perhaps this is something that can > be addressed in UAAG 2.0. the WAI-ARIA 1.0 User Agent Implementation Guide [1] does just this, in particular refer to Supporting Keyboard Navigation [2] There is also a HTML to Platform Accessibility APIs Implementation Guide in development although this is in an earlier stage of development thatn the ARIA guide. The W3C HTML accessibility taskforce [4] is working hard on a range of issues to do with accessibility in HTML5 including the exposing of location information in HTML5 canvas [5], specifically to provide support for screen magnifiers, but we have been getting pushback from certain browsers vendors and people influential in the development of HTML5.
