Exclusive Choice Gateway
Use
An exclusive choice gateway within a rule flow has at least two named branches, one of these being a default one. Each named branch has a condition associated with it. If all the conditions in gateway are not satisfied, then the default condition will be valid and that condition will not be evaluated.
An exclusive choice gateway can optionally have actions and local definitions as in rule scripts so as to assist complex computations if required. It is not a reusable entity in flow ruleset.
