[Read/Write] This is a Boolean property that determines whether an answer is marked as "Unanswered." If so, Unanswered clears the value at that repeat level.
This property is True in the following situations:
Repeated values. Placeholder values are put in the answer file in cases where not all the values at a repeat level are answered. For example if a repeated value is answered at positions 1, 2, and 4 then position 3 will have an unanswered value.
AnswerCollections that have not yet been written to disk. You can create any unanswered values you want in memory. This could happen through an interview or manipulation of the AnswerCollection.
You can use the Unanswered property to delete values from the AnswerCollection. If you set this property to True, then the next time the AnswerCollection is saved to disk, no answer will be saved for that value.
