## Union of http://hl7.org.au/fhir/StructureDefinition/au-composition and http://hl7.org.au/fhir/StructureDefinition/au-composition

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