| Description | 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. |
| Purpose | The order of questions within groups, groups within groups and groups within questions is relevant and must be retained for display and capture for both Questionnaire. The order of answer choices may also be significant. |
| Type | Extension |
