## Intersection of http://hl7.eu/fhir/base-r5/StructureDefinition/allergyIntolerance-eu-core and http://hl7.eu/fhir/base-r5/StructureDefinition/allergyIntolerance-eu-core

This is the set of resources that conform to both Allergy Intolerance (EU core) (http://hl7.eu/fhir/base-r5/StructureDefinition/allergyIntolerance-eu-core) and AllergyIntolerance (EU core) (http://hl7.eu/fhir/base-r5/StructureDefinition/allergyIntolerance-eu-core).
