This may be used for cases when a new GFE is needed or a Task needs to be replaced for some reason and the requester and owner, where present, are the same between the referenced and source Task respectively. package_name: hl7.fhir.us.davinci-pct.r4 derivation: constraint name: GFERelatedTask type: Extension elements: extension: array: true min: 2 index: 0 slicing: slices: relationship: match: {} schema: short: A code indicating the nature of the Task relationship. _required: true index: 1 extensions: {} elements: extension: {index: 2} url: pattern: {type: Uri, value: relationship} index: 3 value: choices: [valueCodeableConcept] index: 5 valueCodeableConcept: {type: CodeableConcept, choiceOf: value, index: 6} required: [value, valueCodeableConcept] related: match: {} schema: short: A code indicating the nature of the Task relationship. _required: true index: 7 extensions: {} elements: extension: {index: 8} url: pattern: {type: Uri, value: related} index: 9 value: choices: [valueReference] index: 11 valueReference: type: Reference choiceOf: value refers: ['http://hl7.org/fhir/us/davinci-pct/StructureDefinition/davinci-pct-gfe-contributor-task', 'http://hl7.org/fhir/us/davinci-pct/StructureDefinition/davinci-pct-gfe-coordination-task'] index: 12 required: [valueReference, value] description: match: {} schema: short: A description of relevant changes or matters of import. index: 13 extensions: {} elements: extension: {index: 14} url: pattern: {type: Uri, value: description} index: 15 value: choices: [valueMarkdown] index: 17 valueMarkdown: {type: markdown, choiceOf: value, index: 18} required: [valueMarkdown, value] url: pattern: {type: Uri, value: 'http://hl7.org/fhir/us/davinci-pct/StructureDefinition/gfeRelatedTask'} index: 19 value: choices: [] index: 21 package_version: 2.0.0 extensions: relationship: url: null short: A code indicating the nature of the Task relationship. _required: true index: 1 extensions: {} elements: extension: {index: 2} url: pattern: {type: Uri, value: relationship} index: 3 value: choices: [valueCodeableConcept] index: 5 valueCodeableConcept: {type: CodeableConcept, choiceOf: value, index: 6} required: [value, valueCodeableConcept] related: url: null short: A code indicating the nature of the Task relationship. _required: true index: 7 extensions: {} elements: extension: {index: 8} url: pattern: {type: Uri, value: related} index: 9 value: choices: [valueReference] index: 11 valueReference: type: Reference choiceOf: value refers: ['http://hl7.org/fhir/us/davinci-pct/StructureDefinition/davinci-pct-gfe-contributor-task', 'http://hl7.org/fhir/us/davinci-pct/StructureDefinition/davinci-pct-gfe-coordination-task'] index: 12 required: [valueReference, value] description: url: null short: A description of relevant changes or matters of import. index: 13 extensions: {} elements: extension: {index: 14} url: pattern: {type: Uri, value: description} index: 15 value: choices: [valueMarkdown] index: 17 valueMarkdown: {type: markdown, choiceOf: value, index: 18} required: [valueMarkdown, value] class: extension kind: complex-type url: http://hl7.org/fhir/us/davinci-pct/StructureDefinition/gfeRelatedTask base: http://hl7.org/fhir/StructureDefinition/Extension version: 2.0.0
