## Union of http://hl7.org/fhir/us/central-cancer-registry-reporting/StructureDefinition/central-cancer-registry-reporting-messageheader and http://hl7.org/fhir/us/central-cancer-registry-reporting/StructureDefinition/central-cancer-registry-reporting-messageheader

This is the set of resources that conform to either of the profiles Central Cancer Registry Reporting Message Header (http://hl7.org/fhir/us/central-cancer-registry-reporting/StructureDefinition/central-cancer-registry-reporting-messageheader) and Central Cancer Registry Reporting Message Header (http://hl7.org/fhir/us/central-cancer-registry-reporting/StructureDefinition/central-cancer-registry-reporting-messageheader). E.g. what you have to deal with if you get resources conforming to one of them
