I suspect that from the average webmasters point of view, HyTime is irrelevant 
(except as possible inspiration) - so XML is indicted, and, I fear, guilty as 
charged.  

There may be a way around this for the average webmaster or hacker, but not 
with the current DTD structure.  Another schema may be capable of handling 
this both transparently and intelligibly.  Hopefully the W3C will take these 
issues into account for both the namespaces proposal and for whatever schema 
we end up with.

More next week, after I finish this list @#X! chapter.  XSchema should be 
ready for final review by early next week, and I'll have time to wonder about 
complexity again.
