Must Support Expectations

The Ontario SDC Questionnaire profile makes use of the mustSupport flag to indicate elements that are essential for conformant behavior across systems.

For purposes of this IG, mustSupport means the following:

• Compliant forms SHALL only make use of elements marked as mustSupport.
• Compliant form fillers SHOULD tolerate the presence of elements and extensions that are not mustSupport, but MAY ignore. all non-mustSupport elements
• For elements that are marked as mustSupport, compliant form fillers SHALL render, enforce data entry and validation rules, and perform calculations or logic as defined by the definition of that element. Ignoring or failing to behave as a mustSupport element requires is non-conformant.
