Right, so using XPointer:

http://example.org/yourSchema.xsd#xpointer(/xsd:schema/xsd:simpleType[@name=
'myUnsignedInt']

would be equivalent to:

http://example.org/yourSchema.xsd#myUnsignedInt

but allow overloading names for types, elements and attributes.

XPointer also allows us to implement collections in RDDL e.g.

<div id="foo">
	<rddl:resource .../>
	<rddl:resource .../>
	<rddl:resource .../>
</div>

=>

#foo/1
#foo/2
#foo/3
