Union of http://hl7.org/fhir/us/core/StructureDefinition/us-core-documentreference and http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-graphic-reference

This is the set of resources that conform to either of the profiles US Core DocumentReference Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-documentreference) and Graphic Reference (http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-graphic-reference). E.g. what you have to deal with if you get resources conforming to one of them
