description: 'Content of one version in a `VERSIONED_COMPOSITION`. A Composition is considered the unit of modification of the record, the unit of transmission in record Extracts, and the unit of attestation by authorising clinicians. In this latter sense, it may be considered equivalent to a signed document.\n\nNOTE: It is strongly recommended that the inherited attribute `_uid_` be populated in Compositions, using the UID copied from the `_object_id()_` of the `_uid_` field of the enclosing `VERSION` object. +\nFor example, the `ORIGINAL_VERSION.uid` `87284370-2D4B-4e3d-A3F3-F303D2F4F34B::uk.nhs.ehr1::2` would be copied to the `_uid_` field of the Composition.' package_name: openehr.base derivation: specialization name: COMPOSITION type: http://openehr.org/fhir/StructureDefinition/COMPOSITION elements: language: {type: 'http://openehr.org/fhir/StructureDefinition/CODE-PHRASE', short: Mandatory indicator of the localised language in which this Composition is written., isModifier: false, index: 0} territory: {type: 'http://openehr.org/fhir/StructureDefinition/CODE-PHRASE', short: Name of territory in which this Composition was written., isModifier: false, index: 1} category: {type: 'http://openehr.org/fhir/StructureDefinition/DV-CODED-TEXT', short: 'Temporal category of this Composition, i.', isModifier: false, index: 2} context: {type: 'http://openehr.org/fhir/StructureDefinition/EVENT-CONTEXT', short: 'The clinical session context of this Composition, i.', isModifier: false, index: 3} composer: {type: 'http://openehr.org/fhir/StructureDefinition/PARTY-PROXY', short: The person primarily responsible for the content of the Composition (but not necessarily its committal into the EHR system)., isModifier: false, index: 4} content: {type: 'http://openehr.org/fhir/StructureDefinition/CONTENT-ITEM', short: The content of this Composition., isModifier: false, array: true, index: 5} package_version: 0.1.0-snapshot class: logical kind: logical url: http://openehr.org/fhir/StructureDefinition/COMPOSITION base: http://openehr.org/fhir/StructureDefinition/LOCATABLE version: 0.1.0-snapshot required: [composer, territory, category, language]
