DMN — What 'I Could Not Decide' Looks Like
The most important template in this set, and the state most decision-table tools never show anyone. The Region column declares no domain, so the checker cannot know whether the rules cover it — and it says so rather than inferring the domain from the rules' own values, which would make every table complete by construction and every completeness report worthless.
Make it your own.
