Bug in 'RDF-Primer'

Hello,

in document

	http://www.w3.org/TR/2003/WD-rdf-primer-20030123/

there's a bug in section 5.2, just above Example 20:

"The meaning of the rdfs:subPropertyOf relationship
is that if an instance ex:fred is an
ex:primaryDriver of the instance
ex:companyVan, then ex:fred is implicitly
considered to also be an ex:primaryDriver of
ex:companyVan."

The last part of that sentence should be:

"...is implicitly
considered to also be an ex:driver of
ex:companyVan."

(ex:driver instead of ex:primaryDriver)
