I agree that we should support the use of WCAG triple-A compliance. But I would prefer to see triple-A compliance (particularly in the case of WCAG) as a requirement for triple-A conformance to UAAG, or perhaps double-A conformance, rather than a requirement for single-A conformance. A double-A compliant tool is not making any claim that it is particularly good for people with disabilities to use, just that it is possible to be more or less effective using it. A level-A conformant tool doesn't even make the claim that it is possible to use it effectively (in the sense that we think of somebody being able to do things in a "reasonable" amount of time and with a reasonable amount of effort). It just claims that it isn't made impossible. My proposal is therefore to resolve this by adding a checkpoint at Priority level 2 or 3 (according to how importantly the groups rates ease of documentation use as a precondition of effective use of a tool), more or less as follows: Ensure that at least one version of the product documentation conforms to at least Level Triple-A of the Web Content Accessibility Guidelines 1.0 [WCAG10].

If triple a comploiance AAA, is meaningful, then it should be required. Surely, defining three levels of compliance was not an idle academic exercise. As Gregory notes, access to documentation is critical. So, if the WAI believes in its own work, it should support it by requiring that it be implemented.
