The Event-Based Gateway represents a branching point in the Process where the alternative paths that follow the
Gateway are based on Events that occur, rather than the evaluation of Expressions using Process data (as with an
Exclusive or Inclusive Gateway). A specific Event, usually the receipt of a Message, determines the path that will
be taken. Basically, the decision is made by another Participant, based on data that is not visible to Process, thus,
requiring the use of the Event-Based Gateway.
