Uses PHP DOM to create DOM document and nodes.

We use namespaces carefully here, although it may create wordy output if the DOM is not optimizing the declarations for us. Still, best to be explicit, it would seem.

The URI used to refer to other resources is based on the source document location, eg http://this.server/taxonomy_xml/{vid}/rdf#{tid}
