Union of http://hl7.org/fhir/uv/ips/StructureDefinition/Observation-pregnancy-edd-uv-ips and http://hl7.org/fhir/uv/ips/StructureDefinition/Observation-pregnancy-edd-uv-ips

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