StructureDefinition-extension-itemOrder
A non-negative integer representing the order of questions within Questionnaires groups, groups within groups and groups within questions and the order of answer choices for questions of type ‘choice’ and ‘open-choice using Questionnaire.item.option. The order values should be consecutive and start at 0 or 1.
Context of Use: Questionnaire.item, Questionnaire.item.option
Implementation Guidance: Note that a the order within an array SHALL be maintained in conformant FHIR implementation. However in practice, this can be difficult to validate and maintain. An explicit order element for Questionnaires item groups and answer choices helps the renderer to preserve the proper order. For example when the resource instance is split up and then reassembled from an application’s internal format.
When using a contained value set representing permitted answers for a ‘choice’ or ‘open-choice’ question use the standard FHIR extension valueset-conceptOrder to indicate the order rank in the same manner as with this extension.
