## Intersection of http://hl7.org.au/fhir/ps/StructureDefinition/au-ps-allergyintolerance and http://hl7.org.au/fhir/ps/StructureDefinition/au-ps-allergyintolerance

This is the set of resources that conform to both AU PS AllergyIntolerance (http://hl7.org.au/fhir/ps/StructureDefinition/au-ps-allergyintolerance) and AU PS AllergyIntolerance (http://hl7.org.au/fhir/ps/StructureDefinition/au-ps-allergyintolerance).
