I'm not talking about processors. I'm simply talking about parsers here. The
RDF spec clearly states in the prose that parsers must accept parseTypes
with other values. That this is not also in the grammar is a mistake. I
don't see how it could be any other way.

Yes, there is clearly something broken here. I explained one bit above, you
referred to two more:

  http://www.w3.org/2000/03/rdf-tracking/#rdfms-xml-literal-namespaces
  http://www.w3.org/2000/03/rdf-tracking/#rdfms-literal-is-xml-structure

a third is in our goal of remaining compatible with DAML and other
implementers (which I feel requires us to provide a response to their work
on daml:collection) and a fourth is:

  http://www.w3.org/2000/03/rdf-tracking/#rdfs-xml-schema-datatypes

I'm sure that there are others.
