Hi Luc and Reza,
There are issues with making Person as subtype of Agent, since we refer to
a Person in many contexts where the Person is not an Agent (e.g. Bob the
person is 50 years old - there is no notion of responsibility to identify
Bob as an Agent in this assertion).

Reza: Can you please suggest a definition for "System"? In many contexts
System is the same as Organization (e.g. Esurance is an online auto
insurance company and a "system").

Trying to model agents from a domain-specific scenario (eRecords, audit) in
the "core" DM will lead to elements that will be incompatible with
requirements of other domains, hence my original suggestion was to move the
subtypes of agent to an "extensibility" or "common elements" sections of
the DM.

Thanks.

Best,
Satya
