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

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