## Union of http://hl7.eu/fhir/eps/StructureDefinition/observation-pregnancy-edd-eu-eps and http://hl7.eu/fhir/eps/StructureDefinition/observation-pregnancy-edd-eu-eps

This is the set of resources that conform to either of the profiles Observation Pregnancy - Expected Delivery Date (EPS) (http://hl7.eu/fhir/eps/StructureDefinition/observation-pregnancy-edd-eu-eps) and Observation: Pregnancy - Expected Delivery Date (EPS) (http://hl7.eu/fhir/eps/StructureDefinition/observation-pregnancy-edd-eu-eps). E.g. what you have to deal with if you get resources conforming to one of them
