| The gateways are mapped to choices, the sequence flows to transitions. The guards of the transitions are derived by the expression or the name of the sequence flow. If there is more than one outgoing flow from an exclusive gateway, the evaluation of the expressions is ordered by their flow names and manifested by the order tagged value. I.e., if the modeler wants to influence this order by use a syntax such as "1: valid", "2: invalid", etc. in the BPMN model. |
