I expect the "instances" to be separate. Attached is a
simple example (based on daml-ex) that I worked up for a
recent BBN talk. It used RDF/RDFS rather than DAML so I
could process it with existing tools -- I think Sergey's
latest RDF API release will support DAML-ONT, but haven't
had a chance to try it myself yet.
