## Union of http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-amount-ratio and http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-amount-ratio

This is the set of resources that conform to either of the profiles Amount Ratio (http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-amount-ratio) and Amount Ratio (http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-amount-ratio). E.g. what you have to deal with if you get resources conforming to one of them
