Very interesting...  I took a quick look at your doc but need to 
digest it further. Hopefully these questions won't be redudant
then. Anyway, I'll risk asking dumb questions:
Can we mechanically fabricate the XML Schema for each RDF
namespace? ie. given a list of properties, classes (and other
resources) described by the RDF, can you auto-generate the XML Schema? 
If not, are there at least some high level similarities amongst these
schemas that could make the task simpler?
