## Intersection of http://hl7.org/fhir/uv/ips/StructureDefinition/AllergyIntolerance-uv-ips and http://hl7.eu/fhir/base/StructureDefinition/allergyIntolerance-eu-core

This is the set of resources that conform to both AllergyIntolerance (IPS) (http://hl7.org/fhir/uv/ips/StructureDefinition/AllergyIntolerance-uv-ips) and AllergyIntolerance (EU core) (http://hl7.eu/fhir/base/StructureDefinition/allergyIntolerance-eu-core).
