Graham,

In

     http://lists.w3.org/Archives/Public/www-rdf-comments/2001JanMar/0027.html

you raised an issue with the RDF recommendations which was captured in

   http://www.w3.org/2000/03/rdf-tracking/#rdfs-clarify-subClass-and-instance

as

[[[
It is suggested that the novel use of subclass and instance relationships 
in RDF will be hard for those familiar with object oriented programming to 
understand and that a clearer discussion of the application of these 
relationships, especially when the same resource is both an instance and a 
subClass would be helpful.
]]]

As recorded in

   http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002May/0028.html

the RDFCore WG has decided to close this issue on the grounds

  - subClassOf and rdf:type are defined in the RDF Model Theory

  - the RDF Schema spec and RDF Primer provide adequate descriptions of 
these properties

The formal wording of the resolution is a bit bare, but basically what this 
means is that the WG has decided that the new model theory document 
(http://www.w3.org/TR/rdf-mt/) provides a clear formal specification of the 
meaning of this construct, and the new rdf primer provides a clear 
(http://www.w3.org/TR/rdf-primer/) informal informal treatment.

Please could you respond to this message, copying www-rdf-comments@w3.org 
indicating whether this is an acceptable resolution of this issue.
