Let me play dumb for a moment (no snide comments please). Given that:

	<a>
		<b idref="1"/>
	</a>
	<c id="1"/>

implies all kinds of relationships between {a,b,c} (even more so if you
define a schema for it), can you expand on your request?  What do you
need that XML doesn't already have?  Are you really asking for a way to
model inter-document (data instance) relationships? Or perhaps an XML
meta-modeling standard of sorts?  In either case, I end up recursing
back to base XML and wondering what else do you need?  Is this really a
request for a better schema language?
