Actually, I meant both modules and profiles ultimately contain
collections of elements and attributes that - in their entirety as a
module or a profile - are not applicable. I am not saying that parts
of them are not useful. I didn't actually see much disagreement
between your explanation and mine in the previous emails of this
thread and was just trying to point out that SMIL is not forgotten and
is referred to as a pool of ideas for solutions.

Is there a demo available publicly?

Rest assured that there are people in the WG that look at SMIL for
sources of solutions. It's just that none of the groupings (the full
SMIL, the profiles or the modules) seemed appropriate thus far. The
problem that HTML is solving with media elements so much smaller than
the problem that SMIL solves that we can only sometimes refer back to
an idea in SMIL.

Best Regards,
Silvia.
