Hi, Yesterday I took an action item to pull out of the alignment list the UAAG checkpoints that support WCAG success criteria at each level (see attached). Then I cross-referenced these with the UAAG Implementation report for HTML 4.01 (see below). Here are some observations: 1. Most of the supporting checkpoints apply to level 1 WCAG success criteria (of the 3 that don't at the moment, I think there is a case that all of them might be "general") - this would simplify things by collapsing the checkpoints into a single "subset of UAAG that directly supports any level of WCAG conformance". 2. Unfortunately, the implementation of this subset of UAAG is not widespread, so the same argument the WCAG-WG used for not requiring UAAG Level A would apply. 3. Compiling such a subset also raises a bigger question...is this a de facto re-prioritizing of UAAG? And if so, this probably isn't a good idea since those priorities were agreed upon as part of W3C process. (my sense is that if we looked through UAAG there's probably more checkpoints that would qualify for the general category anyway - otherwise why are they P1's?) 4. And, as mentioned yesterday, there are probably differences between technologies (e.g. HTML vs Flash) when it comes to the supporting subset. So...perhaps this was a useful exercise, but one that we may want to keep internal.
