This is the set of resources that conform to either of the profiles Identifikator Profil für ein FHIR Data Service der ePA (https://gematik.de/fhir/epa/StructureDefinition/identifier-epa-fhir-data-service) and Identifikator-Profil für ein FHIR Data Service der ePA (https://gematik.de/fhir/epa/StructureDefinition/identifier-epa-fhir-data-service). E.g. what you have to deal with if you get resources conforming to one of them
