## Union of http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest and http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest

This is the set of resources that conform to either of the profiles AU eRequesting CommunicationRequest (http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest) and AU eRequesting CommunicationRequest (http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest). E.g. what you have to deal with if you get resources conforming to one of them
