Union of http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-pregnancyintent and http://hl7.org/fhir/us/pacio-pfe/StructureDefinition/pfe-collection

This is the set of resources that conform to either of the profiles US Core Observation Pregnancy Intent Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-pregnancyintent) and Personal Functioning and Engagement Collection (http://hl7.org/fhir/us/pacio-pfe/StructureDefinition/pfe-collection). E.g. what you have to deal with if you get resources conforming to one of them

effective[x]	SΣ	1..1		left: Clinically relevant time/time-period for observation; right: Clinical relevant time for an assessment such as post-acute care observations performed with structured evaluation tools is the time the evaluation occurs, i.e., when the clinician obtains the answers entered in the tool. However, the only timing available may be when then tool is completed by the clinician. That timing is generally documented as a point in time (dateTime). ele-1: All FHIR elements must have a @value or children
