But (in at least some situations) is not appropriate to record that you know that you
don't have a value?
I think the words of Donald Rumsfeld are appropriate here:
"There are known knowns. These are things we know that we know. There are known unknowns.
That is to say, there are things that we know we don't know. But there are also unknown
unknowns. There are things we don't know we don't know."
