RDF Syntax as XML regular expression

I have created a tree regular expression that defines:

1) a proper XML syntax for RDF 1.0 as a tree regular expression that matches
generic RDF
2) a simplified XML syntax for RDF. This syntax uses the namespace
http://www.openhealth.org/RDF/RDFSurfaceSyntax

See http://www.openhealth.org/RDF/RDFSurfaceSyntax for details.

RELAXNG schemas are available at:
http://www.openhealth.org/RDF/RDF1.rng (RDF 1.0)
http://www.openhealth.org/RDF/RDF.rng (new syntax)

An XSLT transform is available at:
http://www.openhealth.org/RDF/RDFSurfaceSyntax.xsl -- this is in the process
of being upgraded from RDF 1.0 to the new syntax (the rdf:aboutQ and
rdf:resourceQ attributes and some other new features are not yet handled).
