I am currently diving deep into W3C XML Schema datatypes and, without 

wanting to sound negative, I find them far from perfect...


This list is probably not the place to discuss pros and cons of W3C XML 
Schema datatypes, but I think that the mechanism which will be defined 
to bind the datatypes should be generic and extensible enough to allow 
to bind other datatype systems (should any become available)!

I am not sure how relevant this is for RDF, but RELAX NG has also had to 
solve the issue of "pluging" optional datatype systems into an "untyped" 
model and this has been solved by attaching datatype libraries and type 
information identified by a URI (for the library) and a NCName (for the 
datatype in this library):
