## Union of http://hl7.org/fhir/uv/livd/StructureDefinition/observationdefinition-uv-livd and http://hl7.org/fhir/uv/livd/StructureDefinition/observationdefinition-uv-livd

This is the set of resources that conform to either of the profiles LIVDObservationDefinition (http://hl7.org/fhir/uv/livd/StructureDefinition/observationdefinition-uv-livd) and LIVDObservationDefinition (http://hl7.org/fhir/uv/livd/StructureDefinition/observationdefinition-uv-livd). E.g. what you have to deal with if you get resources conforming to one of them
