description: Workflow Status is used to represent details of the value set development process while the value set has an Activity Status of Preliminary. The development of a value set often follows a formal workflow process from initiation to completion, and this element carries the state variable for this state machine. The assumption is that when first created a value set would have a workflow state of Draft. Additional workflow states may be used. package_name: hl7.fhir.r2b.core derivation: constraint name: Indicates the state of development of the value set 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/codesystem-workflowStatus'} type: uri mustSupport: false maxLength: 0 base: {max: '1', min: 0, path: Extension.url} isSummary: false index: 1 value: base: {max: '1', min: 0, path: 'Extension.value[x]'} isSummary: false maxLength: 0 isModifier: false mustSupport: false choices: [valueString] index: 3 valueString: isModifier: false index: 4 type: string 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/codesystem-workflowStatus base: http://hl7.org/fhir/StructureDefinition/Extension version: null required: [valueString, value]
