Question about subproperties from Pierre-Antoine CHAMPIN on 1999-08-17 (www-rdf-comments@w3.org from July to September 1999)

I'm curently working on a RDF application,
and I was wondering about a point :

<rdf:Property rdf:id="P1">
  <rdfs:range rdf:resource="#C1"/>
</rdf:Property>

<rdf:Property rdf:id="P2">
  <rdfs:subPropertyOf rdf:resource="#P1"/>
  <rdfs:range rdf:resource="#C2"/>
</rdf:Property>

in this case, it seems logic to me that C2 must be a subclass of C1,
(or at most to be the SAME class, of course).

Though, this constraint is not explicitely imposed by RDF, or am I wrong ?
