I looked around at other related uses for "asset" - eg from INDECS and RDF, and found that Subject could be useful
as this is the entity used by RDF for indicating the "thing" being described [1] - and may help in our future RDF Encoding work.

INDECS aslo used "item" as the "specific artefact".

Association is too general, as every relation in UML is an association.

In general, Party and Asset have become the two entities that represent real world items, and Role and Subject then become the way we associate them to the Policy.

Like Party/Role - we only need Role in the encoding, we can do the same with Asset/Subject:

 <o:subject uid="http://example.com/report.pdf o:item="o:target"/>

That was my thinking....

Any other suggestions?
