Union of http://hl7.eu/fhir/laboratory/StructureDefinition/Substance-additive-eu-lab and http://hl7.eu/fhir/laboratory/StructureDefinition/Substance-additive-eu-lab

This is the set of resources that conform to either of the profiles Substance: Specimen Additive Substance (http://hl7.eu/fhir/laboratory/StructureDefinition/Substance-additive-eu-lab) and Substance: Specimen Additive Substance (http://hl7.eu/fhir/laboratory/StructureDefinition/Substance-additive-eu-lab). E.g. what you have to deal with if you get resources conforming to one of them
