Peter,


In http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0149.html
you note,
> The RDF Schema document says
>
>	RDF's vocabulary description language, RDF Schema, is an extension
>	of RDF. It provides mechanisms for describing groups of related
>	resources and the relationships between these resources. RDF Schema
>	vocabulary descriptions are written in RDF. The extra descriptive

Would the following revision to the paragraph quoted address your concern:

  "RDF's vocabulary description language, RDF Schema, is a 
   semantic extension([SX]) of RDF. It provides  mechanisms for describing groups
   of related resources and the relationships between these resources. 
   RDF Schema vocabulary descriptions are written in RDF using the terms 
   described in this document."

	ref [SX] RDF Semantics
	    http://www.w3.org/TR/rdf-mt/#intro


If not, could you suggest alternate text.

thanks,

Dan
