description: This profile defines a composition structure that localises core concepts for use in an Australian context. The purpose of this profile is to provide national level agreement on core localised concepts. This profile does not force conformance to core localised concepts. It enables implementers and modellers to make their own rules, i.e. [profiling](http://hl7.org/fhir/profiling.html), about how to support these concepts for specific implementation needs. package_name: hl7.fhir.au.base derivation: constraint name: AUBaseComposition type: Composition elements: extension: index: 0 slicing: rules: open discriminator: - {path: url, type: value} min: null slices: informationRecipient: match: {url: null} schema: {type: Extension, short: Who and/or what should receive a copy of the composition, url: 'http://hl7.org.au/fhir/StructureDefinition/information-recipient', index: 1} min: 0 package_version: 4.2.2-preview extensions: informationRecipient: {url: 'http://hl7.org.au/fhir/StructureDefinition/information-recipient', min: 0, type: Extension, short: Who and/or what should receive a copy of the composition, index: 1} class: profile kind: resource url: http://hl7.org.au/fhir/StructureDefinition/au-composition base: http://hl7.org/fhir/StructureDefinition/Composition version: 4.2.2-preview
