## Union of http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-structure-reference and http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-structure-reference

This is the set of resources that conform to either of the profiles Structure Data Reference (http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-structure-reference) and Structure Data Reference (http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pqcmc-structure-reference). E.g. what you have to deal with if you get resources conforming to one of them
