Implementers need guidance on how to use profile identifier to search for resources compatible with the display characteristics of their client application. There are many data elements that could be included in a resource in the response bundle. However, the client applications are only mandated to display the must-support data elements. Are we expecting application to display other data elements? What should be the expectation of users/clinicians who use client applications that conform to this spec (i.e. the "requestor" actor0?

Summary:

Provide guidance to application that use FHIR to interrogate EHRs for resources conformant with US-Core. The current guidance focuses on the 'responder', primarily.
