The relevant document here is [1] which is not a public document, but incorporates changes from last-call reviews. See, for example, section 4.1.1.2 [2], 4.1.1.3 [3], and appendix C [4]. The client vocabulary schema [4] uses the XML schema datatype as the range of the corresponding RDF property, where the actual value is a literal rather than an RDF class. In this context, the XML schema datatypes are presumed to be subclasses of rdfs:Literal (?). Example of use: <ccpp:Attribute rdf:ID='charWidth'> <rdfs:label xml:lang="en">Character display width</rdfs:label> <rdfs:domain rdf:resource='&ns-ccpp;Component'/> <rdfs:range rdf:resource='&ns-xsdt;integer'/> <rdfs:comment xml:lang="en"> For character displays, the number of characters that can be rendered across the display. For displays using a proportional font, this is the display width in typographical 'em's. </rdfs:comment> </ccpp:Attribute> Ooops, just spotted a couple of bugs in the appendix C schema :-( This raises a couple of questions: What is the data type of a resource that is a DTD?
