[CASHeW-s-editor-patches] FYI: RDF #09

[Andrew John Hughes]

I'm committing the attached patch to finish up the handling
of basic triples in RDF.  With this patch, most shortcuts
should be handled.  Testing shows that it can handle examples
1 to 7 of the RDF XML specification (which follows on from the
primer, oddly enough) and the music OWL ontology produced
by myself and Simon.  The main remaining areas are collections
and parse types.
