Although the primary audience is developers, I know of at least one instance
where the ATAG is used in a legal national law suit against a government,
and as such, the use of the less accurate term "accessible content" may have
a major effect on the outcome of the court case, and may be misleading to
decision makers who are trusting the W3C as accurate.

Jeanne, Jan,

Thanks for the additional clarifications in your replies.

Jan, yes I support a special CG to explore the details of the 
dependency and come back to the groups with options.

Will do a separate thread to check availability for that.
