Description
The definition says that it indicates "roles", when in fact it represents a single role. The usage notes also don't make it clear that one of the intended uses of this resource is to allow identifying a Practitioner "in a particular capacity and on behalf of a particular organization". That's how the resources is most commonly referenced, so the description should call out that it can be used to refer to "Dr. Smith, chief cardiologist at Hospital X" or "Dr. Smith at Hospital X" or "Chief cardiologist at Hospital X" or "Dr. Smith, as chief cardiologist" and similar combinations of the 3 primary elements of practitioner, organization & role.
We should be specific that if you point to PractitionerRole, the assertion is that the individual is acting "in that capacity". I.e. If you point to the PractitionerRole linked to Hospital X, that means they're acting on behalf of Hospital X. If you want to record that they are acting on behalf of a different organization, it must use a different PractitionerRole.
Finally, the change of PractitionerRole.code to 0..* is problematic because if multiple codes are specified, how can you tell what "capacity" the individual was acting in? It's not ok to say they were acting in capacity A or B. We could allow for them to be acting in both capacities simultaneously, or we would have to have a distinct PractitionerRole for each capacity so that when a linkage is made it's clear which capacity is relevant.
In general, need to clarify the use of this resource when it's identifying an actor as opposed to when it's just appearing in a registry and identifying relationships. The work group needs to recognize that most systems will only deal with PractitionerRole as an actor, not as a registry entry and take this usage into account when making changes to the resource.
