Topic: Observation.component[x].dataAbsentReason
Nick George (Mar 11 2021 at 19:09):
Question about https://www.hl7.org/fhir/observation-definitions.html#Observation.component.dataAbsentReason
This lists invariant
dataAbsentReason SHALL only be present if Observation.value[x] is not present dataAbsentReason.empty() or value.empty()
But that seems more a comment on the root Observation.dataAbsentReason.
I'd expect a fhirpath expression on Observation.component requiring Observation.component.value[x] to be empty if Observation.component.dataAbsentReason is set. Does that seem reasonable? happy to file a ticket if so

Also potentially a fhirpath on Observation that if dataAbsentReason is set, then sizeof component == 0
Eric Haas (Mar 11 2021 at 20:26):
may already be a ticket so should check first.
