RDFS extends RDF by assigning a semantics to particular RDF
constructs. For example, the property "subClassOf" is given a
(relatively informal) semantics in the RDFS specification. The same
should be true for DAML-ONT - it extends RDF/RDFS by assigning a
semantics (preferably well defined) to certain constructs. It is
pointless to say that we rely on the semantics of the host language
(RDF/RDFS in this case) as in this case we are not extending it, just
writing something down in it - I can say x subClassOf y in RDF, but it
doesn't have any meaning beyond the fact that x is related to y by
some relation that just happens to have the name subClassOf.
