summary if issue from Mark Tucker
A message is like a function call f(x,y).
An application needs to be able to define what function calls it supports
f(x,y)  - patient admit
g(x) - patient discharge
For ADT there is not much wanted back from a function call, but there may be some expectations of information back or other receiver responsibilities.


T.f(x, y) 
HL7 does not use receiver responsibilities much, and the suggestion is that interactionIds should not include defining the receiver responsibilities -- these are more often locally defined.  What happens when the same message is used in different contexts -- split: 
the conversation definition (receiver responsibilities) 
the trigger event (why this message was sent)
the static model definintion.

The "message" is the package -- it has a label and a content

We need the event identifier to be separated from the definition of the content and communication identifier
