DMNFTF — No way to associate to a Decision the ItemDefinition of its outcome without defining decisionLogic

Whereas the items from InputData can be defined by associating an ItemDefinition to the InputData element, the only way to define the outcome of a decision is by associating a decisionLogic to the Decision, and an ItemDefinition to the decisionLogic.

Proposal: Add an outcomeDefinition association that is an ItemDefinition to Decision, and make the itemDefinition of a decisionLogic a derived attribute (or otherwise constrain the itemDefinition of the decisionLogic to be the same as the outcomeDefinition of the owning Decision).

Proposed resolution to add an optional outputDefinition attribute to the Decision element, and to require that the output definition of a decision be the same as the item definition of its decision logic, if they are all specified.
