We need to be clear on how seriously DAML-ONT takes the idea of extending RDFS. Referring again to OIL, one of the guiding principals in the design was that as much as possible of a given ontology should be understood by an RDFS agent. This is why OIL class "definitions" are the way they are - they are designed so that an assertion of the form "x = a1 AND ... AND an", which is a VERY common idiom in ontologies, can at least be interpreted by RDFS agents as meaning "x subClassOf a1" AND ... AND "x subClassOf an". This does not seem to have been given much consideration in the RDFS serialisation of DAML-ONT.
