Hi all, Re: an old action item of mine...I received a reply from WCAG-WG... they won't be changing their section A.2.2 but it doesn't prevent us from putting things in a different way that we consider easier to understand.

The proposed reorganization reuses handles, since different conformance levels include different requirements for the same media types.
