## Union of http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-allergyintolerance and http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-allergyintolerance

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