DMN12 — Alternative DRD representation of BKM

(raised by Bruce)
By allowing reuse of a value expression, BKMs provide useful semantics. But their representation in DRD adds visual complexity without a lot of value. The Chapter 11 example in the spec is a good example. Representing both the calling decision and the called BKM in the diagram effectively doubles the number of elements in the DRD, while the knowledge requirement connector does not reveal the elements used in the BKM value expression. As an alternative, a distinctive marking in the DRD of a decision invoking a BKM could provide virtually the same information without adding clutter to the diagram. Since DRD is a filtered and truncated view of the DRG, a tool could already do this today, but not in any standardized notation.
