description: A human language representation of the concept (resource/element), as a url that is a reference to a portion of the narrative of a resource ([DomainResource.text](narrative.html) or [Composition.section.text](composition-definitions.html#Composition.section.text)).  To provide human language maintained separately from the narrative, use [originalText](StructureDefinition-originalText.html). To cross-link narrative and data, use the [textLink extension](StructureDefinition-textLink.html).
