What is "profile" between PUA and Presentity?

I suppose that what you identify is Presentity is a publishing PUA,
i.e., the element which changes presence state. (presentity refers 
merely to the presence identifier rather than  to an element). 
I guess my terminology is not 100% aligned with today's presence 
terminology either.

it is worth mentioning that the publishing element does not need
SIP. (there is no standard in the IETF anyhow) It may publish
the presence document through some local interface to the presence
server.

In general, I think that presentities may publish
