  "description": "An extension to provide the type of an AllergyIntolerance resource, without the need of using the _required_ binding present on `AllergyIntolerance.type`. Note that in R5 this binding has been made _preferred_, making this extension technically a pre-adopt. This extension should be replaced by the extension 'http://hl7.org/fhir/5.0/StructureDefinition/extension-AllergyIntolerance.type' whenever it's made available as part of the package hl7.fhir.extensions.r4:4.0.1 mentioned on http://hl7.org/fhir/R5/versions.html#extensions.",
  "purpose": "This extension represents the type of an AllergyIntolerance resource, needed to distinguish between HypersensitivityIntolerance and Reaction building blocks for implementations following the information standard [CiO](https://informatiestandaarden.nictiz.nl/wiki/Landingspagina_Contra-indicaties_en_Overgevoeligheden).",
