Yep - not ignoring the unknown namespaced elements/attributes. With RDF/XML
partial knowledge can be inferred from the structural relationships between
the XML entities, the clearest example being 'striping':

<x:a>
	<y:b>
		<z:c/>
	</y:b>
</x:a>

Assuming x:a is an rdfs:Class, the application can tell that y:b is an
rdfs:Property and z:c is another rdfs:Class.

Additionally, if the application knew the namespace y: (i.e. it had the RDF
schema for it) there may be domain and range restrictions for the property
y:b, from which the application can infer rdf:type's for x:a and z:c,
without knowing anything else about x: and z:.

Cheers,
Danny.
