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.uv.extensions.r5 derivation: constraint name: ObjectClassProperty type: Extension elements: extension: {index: 0} url: pattern: {type: Uri, value: 'http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty'} index: 1 value: choices: [valueCoding] index: 3 valueCoding: {type: Coding, choiceOf: value, index: 4} package_version: 1.0.0 extensions: {} class: extension kind: complex-type url: http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty base: http://hl7.org/fhir/StructureDefinition/Extension version: 1.0.0 required: [valueCoding, value]
