RE: Combing checkpoints 1.2 and 1.3

The only trouble is that the purpose of 1.3 was to require a description
that could be audible-ized.    That is -- an audio description   (until
the text equiv could be read by screen readers - in which case it would
automatically fulfill this requirement).

By combining these two -- we now require that the text version be
synchronized but we do not require an audio version exist (though if you
did one you would need to synchronize it).   In effect we would remove
audio descriptions for movies from the guidelines.

Now one could say that the criteria would add that back in.  But I don’t
think we can have criteria for a point require something that is not
covered by the point itself.

We tried to fit 1.3 into 1.2 in the first place and were unable.  That
is how we ended up with it as a separate item.   It still needs be
separate unless we can figure out at way to specifically require this in
the checkpoint -- which the current (revised) 1.2 does not

         I've read the combined new 1.2 and it seems to cover everything

that was covered before.  Go for it!
