Thanks Bill.  That helps.  I will copy the X3D list with that.  There is 
an open source implementation in Java that someone might wish to experiment 
with.  Right now, I wish to clearly separate the means of extensibiity 
(eg, registry of types for the object model) from the means of denoting 
that, ie, the use of RNG declarations.

Yes. The rule of thumb; for attribute values or element content use 
plugin datatypes, for structures use RNG itself.

The jing distro has a full example on how to implement this stuff 
and jing itself supports xsd types. If you're good to use java 1.4 
James Clark has mapped WXS' pattern facet to Java regexes.
