This is a first list of questions re requirements for an "accessibility description language", based on the discussion in the joint ER/AU meeting [1] This can be an outline for item 2 of our Monday telecon [2] - what shall we call this? How about "Accessibility description Language" (ADL). To which of the following should it apply? XHTML Any XML application, e.g. SVG? HTML HTML with syntax errors (what severity of errors can be allowed?) CSS ECMA Script Other programming languages CDATA What level should description point to? Characters? Tokens? Tags? ("tags" is html and xml specific... what about other parsable languages?) Shall we include application testing specifications, e.g. a description of steps activating a link filling in a form submitting a form in addition to accessibility in the result? Include summary statistics in output? Combine results of different tools? Retain what tool said what? Include history of what was checked (e.g. "this alt text is OK according to a human") How robust in face of changed source? I.e. if source changes, how much of previous description can carry over? How scalable? Just pages? Whole site? Results of several independed processes running on site? What tools will read output? - evaluation tools - authoring tools Is output useful for user agents? What list of checkpoints to point to? Where maintained? files could be distributed in several files... in one file... so human readable What variations in input cause no change in pointers? added white space? Case? attribute order?
