This is great.

I presume that the new nature for XML Schema ought be
http://www.w3.org/2001/XMLSchema

This gets me thinking about RDDLs interactions with URI persistance
policies - it would be good if in some way we can say:

xxx URI is equivalent to yyy URI
... so when you ask for something with xxx nature, treat something with yyy
nature as equivalent.

xxx URI is a subset of yyy URI
... so when you as for something with yyy nature accept something with xxx
nature

what do people think? how should we handle the issue of new versions of
stuff?
