I don't think that is true;  I see this example in the XMP spec

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:xmp="http://ns.adobe.com/xap/1.0/">
<rdf:Description rdf:about="">
<xmp:BaseURL rdf:resource="http://www.adobe.com/"/>
</rdf:Description>
</rdf:RDF>

Isn't this the same as

<> xmp:BaseURL <http://www.adobe.com/> . ?
