This is the base profile from which the other results profiles are derived. It is informed by the constraints of the [Observation Results IPS-UV profile](http://hl7.org/fhir/uv/ips/StructureDefinition-ObservationResults-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-observation.html) to allow for cross-border and cross-jurisdiction sharing of result information",
