## Union of http://hl7.org/fhir/uv/ipa/StructureDefinition/ipa-medicationstatement and http://hl7.org/fhir/ca/baseline/StructureDefinition/profile-medicationstatement

This is the set of resources that conform to either of the profiles IPA-MedicationStatement (http://hl7.org/fhir/uv/ipa/StructureDefinition/ipa-medicationstatement) and MedicationStatement Profile (http://hl7.org/fhir/ca/baseline/StructureDefinition/profile-medicationstatement). E.g. what you have to deal with if you get resources conforming to one of them
