## Union of http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest and http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest

This is the set of resources that conform to either of the profiles CRD Communication Request (http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest) and CRD Communication Request (http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest). E.g. what you have to deal with if you get resources conforming to one of them
