forest grammar/tree regular expression for RDF

I hope the RDFCore WG will consider the forest grammar/tree regular
expression as a specification of the formal RDF XML syntax. The unordered
nature of RDF is best described as a forest grammar and this presents
difficulties for traditional XML schema languages such as DTDs.

I have specified this as a RELAXNG schema for RDF in terms of solidifying the RDF XML
syntax under the issue:

An advantage of specifying the grammar in this language is that it has a
good formal semantics which is based on the formal semantics of XDuce. . Note that the XML Schema
formalism in appears to be based on
XDuce as well which is referenced.

Because I realize the politics around RELAXNG, I have converted this to the
language used by XDuce and by the XML Schema Formalism:

It is really quite simple.
