Hi again,

I've updated this to include support for nested elements. 

		<foaf:Person hr:qname="pd:phildawes">
			<foaf:name>Phil Dawes</foaf:name>
			<foaf:homepage uri="http://www.phildawes.net/"/>
			<pd:commutesTo hr:qname="pd:city/London"/>
			<pd:eats hr:qname="pd:cabbage">

Still no anonymous nodes yet tho.
