Union of http://hl7.org/fhir/uv/ips/StructureDefinition/AllergyIntolerance-uv-ips and http://hl7.org/fhir/us/core/StructureDefinition/us-core-allergyintolerance

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