My point exactly - why create a new set to replace the existing?

Yes, it's so, RDF-aware processors don't have to know any DAML.  And RDF
would be just one possible way to transport DAML statements.  GIven that XML
will no doubt underlie any other DAML-transport scheme (for web
applications, anyway), you don't suggest that the xml parser should
understand DAML, do you?  The real question seems to be whether RDF will be
an adequate container for DAML.  If so, better to use it so that standard
RDF parsers, etc., can be used to support a DAML engine.  Going a step
further, if you do use RDF should the DAML database (or statementbase)
consist of triples - thus keeping the RDF model in play in the DAML
processing - or not?

Lots of people are interested in this one, I've noticed.  There have been
some recent posts about it in either this list or www-rdf-interest@w3.org
(or probably both, but I haven't searched for them).
