DMN — Shipping Band by Weight and Destination

Two enumerated columns and one numeric one, covered completely. The pattern worth learning is the declared domain: weight is bounded [0..30] and destination is enumerated, so 'complete' means something — without the declaration the checker could only say it did not know.
