I agree with the proposal that assessment, diagnosis belong to the domain of
clinical care.

Do you intend to differentiate an obsevation in the pathophysiological realm 
and the representation of that observation in a medical record?

Isn't that the difference between what is an observation and how it is
represented in a document?
So Clinical Care realm would contain models such as CCD, CDA, etc?
