Sorry I was not clear. What I meant to say was that there were things that
needed to be improved in SMIL if we wanted to make that the (or one of
the) solution(s). I did not mean to say it could not be improved/appended.

I actually think the things I mentioned can be addressed in SMIL without
too much effort.
