description: The FHIR Range datatype uses Simple Quantities to represent the high and low bounds, which do not allow a comparator to be set. This extension allows the high and low bounds to have a comparator package_name: hl7.fhir.us.pq derivation: constraint name: TargetRange type: Extension elements: extension: short: ValueNumeric (range) array: true min: 2 index: 0 slicing: slices: low: match: {} schema: mustSupport: true _required: true index: 1 extensions: {} elements: extension: {index: 2} url: pattern: {type: Uri, value: low} index: 3 value: mustSupport: true choices: [valueQuantity] index: 5 valueQuantity: {type: Quantity, mustSupport: true, choiceOf: value, index: 6} value[x]: elements: value: {mustSupport: true, index: 7} unit: {mustSupport: true, index: 8} required: [value, unit] required: [value, valueQuantity] high: match: {} schema: mustSupport: true _required: true index: 9 extensions: {} elements: extension: {index: 10} url: pattern: {type: Uri, value: high} index: 11 value: mustSupport: true choices: [valueQuantity] index: 13 valueQuantity: {type: Quantity, mustSupport: true, choiceOf: value, index: 14} value[x]: elements: value: {mustSupport: true, index: 15} unit: {mustSupport: true, index: 16} required: [value, unit] required: [value, valueQuantity] url: pattern: {type: Uri, value: 'http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-target-range'} index: 17 value: choices: [] index: 19 package_version: cmc-fda-2.0.0-ballot extensions: low: url: null mustSupport: true _required: true index: 1 extensions: {} elements: extension: {index: 2} url: pattern: {type: Uri, value: low} index: 3 value: mustSupport: true choices: [valueQuantity] index: 5 valueQuantity: {type: Quantity, mustSupport: true, choiceOf: value, index: 6} value[x]: elements: value: {mustSupport: true, index: 7} unit: {mustSupport: true, index: 8} required: [value, unit] required: [value, valueQuantity] high: url: null mustSupport: true _required: true index: 9 extensions: {} elements: extension: {index: 10} url: pattern: {type: Uri, value: high} index: 11 value: mustSupport: true choices: [valueQuantity] index: 13 valueQuantity: {type: Quantity, mustSupport: true, choiceOf: value, index: 14} value[x]: elements: value: {mustSupport: true, index: 15} unit: {mustSupport: true, index: 16} required: [value, unit] required: [value, valueQuantity] class: extension kind: complex-type url: http://hl7.org/fhir/us/pq-cmc-fda/StructureDefinition/pq-target-range base: http://hl7.org/fhir/StructureDefinition/Extension version: 2.0.0-ballot
