The special-value codes that stand for a figure, and the figure. 2222222222,
"nichts vorhanden", is the Destatis symbol -: nothing there, exactly zero — 372
Kreise of AI019-3-5 in 2025 carry it — so it becomes 0, while missing still names
the code. (The upstream also writes it for a Veränderungsrate without a previous year,
AI002-1-5's ai0201v in 2000; missing is how a caller can tell.) Every other code
stays null.
