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

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