Items asked

The PublicSchema property IDs that were actually asked during this administration. Lets adopters distinguish items that were asked and declined (answer absent) from items that were not asked at all. When omitted, the item set is assumed to be the default item_set of the instrument used. The intended producer is the form compiler or collection server, which populates this list from the form definition at submission time.
