Ontology language, message content, instances (DAML+OIL)

My question relates to how an ontology language (XML-based) like DAML+OIL 
can be used to express message content when heterogeneous agents have 
agreed on the ontology. Is it appropriate to only describe instances in 
the message content, and then let the other agent interpret it with the 
agreed defintion.

My understanding is that the whole idea of XML is metadata and data. So 
my whish to remove the metadata in message content is not a nice thought. 
Anyway, are there any nice ways to do this or are there other languages, 
complementary to the ontology languages, more appropriate for message 
content?

Thank you!

Kind Regards,
Lars Ilebrekke
