I'll try...

I think it does more types (as you point out, NOTATION and ENTITY), but 
while it's had a copule of bug-fixes, it's pretty inactive.

Right now it supports only the types that can be serialized as a SOAP 
RPC Encoding item.

I don't have a lot of time to spend on ZSI, unfortunately.  Certainly if 
it became the basis of a type library, I'd have an opinion on how to do 
facets, add other types, etc.  My initial reaction would be to add a 
"check_constraints" method to each TC class ...

I'll do what I can, and hopefully others would find it useful to move 
forward.
