## Union of http://hl7.org/fhir/StructureDefinition/SimpleQuantity and http://hl7.org/fhir/StructureDefinition/SimpleQuantity

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