>Interoperability with JAWS should never be used as an indicator of sufficiency.  Determining if sufficient programmatic information is made available via the various mechanisms involved is the determiner--JAWS may use the information or not, but many use other tools for access.  Writing code to any specific AT should imply it is the only solution within a defined environment which does happen, but WCAG is not an environment specific set of techniques.
