description: For items of type reference, the reference can be populated either by picking an existing entity or by creating a new one.  In the latter case, this Questionnaire allows specifying the Questionnaire to use in creating the target instance.  This can be direct (if the Reference is to a Questionnaire) or indirect via mapping if the Reference is to some other sort of resource.
