WSDL RDF mapping update: dropped unknown extensions, added reuse of SAWSDL

Hi all, 

this is just to notify the group that I made two changes in the latest
version of the RDF mapping, in case anybody cares. 8-)

The first one is that I dropped the mapping of unknown extensions and 
of documentation into XML literals in the resulting RDF. The rationale
is that keeping them would require the use of canonicalization, which 
I believe would be undue burden on the implementations of this mapping,
while the XML literals aren't really useful in the RDF form.

The second change is that instead of modeling SafeInteraction as 
a subclass of InterfaceOperation, it is now a standalone class, and
instead of rdf:type (is_a) relationship between safe operation
components and this class, I now use sawsdl:modelReference for this.
This reuse does not introduce any dependency from our spec to SAWSDL,
nor does it mean that WSDL RDF mapping implementations would need to
understand SAWSDL. As written before, I believe this is the correct
modeling.

This change could, however, have impact on publication of the RDF
mapping WG note (and on nothing else), should the WG note have to wait
until SAWSDL is in Rec. Nevertheless, I hope that the note can be
published together with the other WSDL specs.

Best regards,
Jacek
