DMN — Decision Requirement Diagram, No Table

The structural half of DMN on its own: decisions, input data, business knowledge models and knowledge sources, with the requirement kind derived from what sits at each end rather than spelled out a second time. The engine reports each decision as having no table, which is correct and is the point — this is the diagram DMN work starts from, and those findings are the list of tables still to write.
