>>maybe there is a way to make that point more clear, but language is
evading me for the moment<<

I would think that information to clarify the provision could be covered in
the guidance that should be developed.

I really think we have included most of the items on our list in the 6
recommended standards for 1194.24. it took me a couple reads to follow
(f) however, to understand that it does include a requirement for audio
for menus in reality. Because of this, maybe there is a way to make
that point more clear, but language is evading me for the moment.

As Larry said, nice job to all.

At last, I've posted the following first-draft revisions on the wiki:

-- 1194.24a-b: http://teitac.org/wiki/Revisions_to_1194-24a-b
-- 1194.24c-f: http://teitac.org/wiki/Revisions_to_1194-24c-f

For convenience, I've also pasted them below. These revisions have been
sent to Mike and Jim using the template they sent around a few weeks
ago.

Thanks.
Geoff.
