      "comment" : "the URI refers to an ElementDefinition in either a [StructureDefinition](structuredefinition.html#) or a [DataElement](dataelement.html#), and always starts with the canonical URL for the target resource. When referring to a StructureDefinition, a fragment identifier is used to specify the element definition by its id [Element.id](element-definitions.html#Element.id). E.g. http://hl7.org/fhir/StructureDefinition/Observation#Observation.value[x]. In the absence of a fragment identifier, the first/root element definition in the target is the matching element definition. Note that [LOINC codes](loinc.html#dataelements) implicitly define DataElement resources.",
