Hi George & co,

Well this mail has certainly kicked off some discussion :) Very glad
to see all the energy people have put into this. it would be great to
have Accessibility support mentioned in EPUB 3.01.

Could you expand a little on your comment "a status of accepted public
draft or better is necessary for inclusion in the spec."? Is it
sufficient for to say "we'll do something based on this
draft", or is a commitment to a specific and exact set of
property/type definitions called for?

I think it's fair to say that we ( want to do something in
this area, and that developing the proposal in is how we'll work on
getting there.

The open issues list in shows
that various points are still under healthy discussion in the
community, including discussion of possible property renamings. Given
this week's lively discussion I think it it clear that a lot of people
are enthusiastic to help work out these remaining issues, but that it
could be hard at this point in time to know exactly what the result of
that process will give us.

Could you help by giving more detail on what you'd hope the ultimate
outcome here might be? Would you want to include a specific list of Accessibility properties into an EPUB 3.01 specification,
or would such a specification instead say something closer to "please
use the accessibility vocabulary [cite]"?

Thanks for any advice,
