Watch the modal verbs!  Property names *must* be associated with a
schema, but this can (i.e. *may*) be done by making the URI to
which the namespace prefix is bound the actual URI of the schema

There may be other ways to do it.  Besides, RDF is free to set
tighter limits on the URIs used to identify namespaces than
XML in general.  XML-based standards can always set extra
requirements, like the SMIL requirement (clause 5.1) that there be no
internal DTD subset in SMIL documents.
