<status value="active" /> <description value="Gait group panel observation (custom LOINC 10000-F). This is a panel with no top-level value. Individual gait metrics are expressed as component entries using custom LOINC codes from http://alticelabs.com/fhir/loinc-custom. Components MAY include interpretation and referenceRange when a matching ObservationDefinition exists. Not all components will have UCUM units (e.g., Analysed Steps uses a unitless integer).
