[Jacco] What I tried to say is that HTML+TIME uses elements from SMIL in 
HTML, and that this can be seen as just a special case of the problem of
mixing elements from multiple DTDs in general. Solving this problem is 
probably behind the scope of the HTML and SYMM groups, since it involves 
issues (partly) addressed by XML namespaces and XML architectures 
(a la XLink),  mixing HTML/XML etc.

[Jacco] Can you explain the difference betweeen timing and
synchronization markup?
