description: This profile ensures systems support important Coding elements, including system, code, and display. It also raises awareness of the FHIR Core [translation](http://hl7.org/fhir/StructureDefinition/translation) standard extension.\n\nThis profile is informed by the constraints of the [IPS-UV Coding](http://hl7.org/fhir/uv/ips/StructureDefinition-Coding-uv-ips.html) profile. Unlike IPS, however, the PS-CA profile does not flag the translation extension as Must Support; this may change in future releases. package_name: ca.infoway.io.psca derivation: constraint name: CodingPSCA type: Coding elements: system: {mustSupport: true, index: 0} version: {index: 1} code: {mustSupport: true, index: 2} display: mustSupport: true index: 3 extensions: translation: {url: 'http://hl7.org/fhir/StructureDefinition/translation', type: Extension, short: Language Translation (Localization), index: 5} elements: extension: index: 4 slicing: rules: open discriminator: - {path: url, type: value} min: null slices: translation: match: {url: null} schema: {type: Extension, short: Language Translation (Localization), url: 'http://hl7.org/fhir/StructureDefinition/translation', index: 5} package_version: 2.1.0-DFT-Ballot class: complex-type kind: complex-type url: http://fhir.infoway-inforoute.ca/io/psca/StructureDefinition/Coding-ca-ps base: http://hl7.org/fhir/StructureDefinition/Coding version: null
