          The date at which a concept was deprecated. Concepts that are deprecated but not inactive
             can still be used, but their use is discouraged, and they should be expected to be made

          The concept is not intended to be chosen by the user - only intended to be used as a selector
             for other concepts. Note, though, that the interpretation of this is highly contextual;
