The document at http://www.w3.org/2000/01/rdf-schema# was not updated
to track the changes in the April 2002 RDF Schema WD. We hadn't
put out a new RDFS doc for a while, so I think it was good to test the 
water first. I have an action somewhere to get this updated.

In the meantime, see

http://www.w3.org/TR/rdf-schema/

[[
This RDF/XML is also available as a separate RDF/XML document 
(rdfs-namespace.xml). It is not currently published at the W3C RDF 
Schema namespace URI.
]]
- ->
http://www.w3.org/TR/2002/WD-rdf-schema-20020430/rdfs-namespace.xml

for the updated RDF/XML RDFS document that does have isDefinedBy.
