currently we have:
"An RDF description of the RDF Core vocabulary is given here in RDF/XML
serialization syntax."

I'd accept that "An RDFS description of ..." would be more appropriate.

Then the question of what we're describing. Currently we _do_ describe
both the RDF namespaces owned/managed by RDF Core, ie. 
http://www.w3.org/2000/01/rdf-schema# but also the older 
http://www.w3.org/1999/02/22-rdf-syntax-ns# so our RDF/XML appendix 
includes claims such as:

[[
<rdfs:Class
rdf:about="http://www.w3.org/1999/02/22-rdf-syntax-ns#Property">
  <rdfs:isDefinedBy
 rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#"/>
<rdfs:label>Property</rdfs:label>
<rdfs:comment>The class of RDF properties.</rdfs:comment>
<rdfs:subClassOf rdf:resource="http://www.w3.org/2000/01/rdf-schema#Resource"/>
</rdfs:Class>
]]

I believe it is useful to present an integrated RDFS description of both 
sets of classes and properties, since people can never remember which 
lives where, and the rest of the RDFS spec also describes both.

So question is how to describe this in Appendix A. How about this:

"An RDF description of the RDF Core vocabulary is given here in RDF/XML
serialization syntax."
->
"An RDFS description of the http://www.w3.org/1999/02/22-rdf-syntax-ns#
and http://www.w3.org/2000/01/rdf-schema# vocabularies is given here in 
RDF/XML syntax."

Kinda ugly, but perhaps less contentious?
