XTM uses a simplified XLink syntax.

--conversely there are people who are hoping that XTM '2.0' will be seen as
an application of RDF (model and syntax).

SOAP, I think, is simply akin to a very simplified RDF syntax in which the
attribute abbreviated RDF form is disallowed.

A primary reason why XTM and SOAP/XP are not a good fit as they are today is
that XTM uses a simplified XLink which is attribute based and SOAP is
element based (though one can encode anything in 'SOAP' via an extension
syntax but doing this solves no problem.

My personal view of RDF 2.0:

1) Keep the model
2) Fix the RDF syntax
3) Define mappings of XLink, TM, SOAP etc -- and arbitrary XML -- allowing
parsing of such various syntaxes as RDF model triples

    -- of course by assuming rdf:parseType='Resource' and implementing
XLink2RDF and fixing qname<->URI this is pretty much what you get.
