description: This extension is used on elements of type code to indicate that it's deliberate and appropriate that they not have a binding. Typically, this is because they are contained by another type that does have a binding, but there are other reasons. This is provided to assist with QA processes that can use this to be informed where bindings are not necessary or appropriate. package_name: hl7.fhir.uv.tools.r5 derivation: constraint name: NoBinding type: Extension elements: extension: {index: 0} url: pattern: {type: Uri, value: 'http://hl7.org/fhir/tools/StructureDefinition/no-binding'} index: 1 value: choices: [valueBoolean] index: 3 valueBoolean: {type: boolean, choiceOf: value, index: 4} package_version: 0.4.0 extensions: {} class: extension kind: complex-type url: http://hl7.org/fhir/tools/StructureDefinition/no-binding base: http://hl7.org/fhir/StructureDefinition/Extension version: 0.4.0 required: [value, valueBoolean]
