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/> . ?
