I am still unclear about the definition of a function vs unit &
service.

I do believe that since the PWG has found 1212 to be normative the
1212 definition and the PWG definition should serve the same purpose.

First of all,
The defintion of "function" is for p1212r FDS purposes.
We may not even have to define "function" for the PWG profile, but it is needed
for FDS.
I apologize if I should of done this in the 1212 reflector.

It CAN be considered that way in a ceratin implementation, but we CONNOT
say that is the ONLY way we have to see it.
(Especially in the case of FDS, where we have to start thinking
about other protocols.)
At one point in the discussison, Brian had mentioned that some people may
consider a service as a function, and visa-versa. I agree to this idea, and I gu
ess
we are not allowed to give an answer (restriction) to the relationship between a
function and a unit.
We agreed a unit corresponds to a driver (in the case of the PWG profile).
If so, the relationship of a driver to a function is implementation specific.

The only restrictions I think I can make for "function" are :

1) A part of the unit architecture (not meaning a part of the unit, but meaning
a part of this architecture i.e. part of a node, module, or whatever)
2) A collection(meaning 1 or more) of services
3) User identifiable

I cannot think of more resrtictions to add and still make the definition consist
ant
within 1212
