#remove_device_carrier ⇒ Object

ONC and US Core 4.0.0 both clarified that health IT developers that always provide HL7 FHIR “observation” values are not required to demonstrate Health IT Module support for “dataAbsentReason” elements. Remove MS check for dataAbsentReason and component.dataAbsentReason from vital sign profiles and observation lab profile. Smoking status profile does not have MS on dataAbsentReason. It is safe to use profile.type == ‘Observation’
