description: A quality common to all members of an object class. A property may be any feature that humans naturally use to distinguish one individual object from another. It is the human perception of a single quality of an object class in the real world. It is conceptual and thus has no particular associated means of representation by which the property can be communicated. package_name: hl7.fhir.r2b.core derivation: constraint name: Object Class Property type: null elements: extension: isModifier: false name: extension mustSupport: false maxLength: 0 base: {max: '0', min: 0, path: Extension.extension} isSummary: false index: 0 url: isModifier: false pattern: {type: Uri, value: 'http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty'} type: uri mustSupport: false maxLength: 0 base: {max: '1', min: 0, path: Extension.url} isSummary: false index: 1 value: isModifier: false mustSupport: false choices: [valueCoding] maxLength: 0 base: {max: '1', min: 0, path: 'Extension.value[x]'} isSummary: false index: 3 valueCoding: isModifier: false index: 4 type: Coding mustSupport: false maxLength: 0 base: {max: '1', min: 0, path: 'Extension.value[x]'} choiceOf: value isSummary: false package_version: 1.4.0 extensions: {} class: datatype kind: datatype url: http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty base: http://hl7.org/fhir/StructureDefinition/Extension version: null required: [valueCoding, value]
