Exclusive Gateway

Element
Description	Use the Exclusive Gateway to model a decision in the process. The process will continue with the sequence flow where the defined condition is true. You can also define a default sequence flow (see Particularity). If you use an exclusive gateway, only one sequence flow is selected. If you have modeled multiple sequence flows, make sure they are mutually exclusive. If more than one sequence flow is true, a random decision is made as to which of the processes the process follows. If no condition evaluates to true and you have not defined a default flow, the xUML Runtime will throw an exception. We recommend avoiding this scenario.
Attributes	Name Description Sequence Flow Type (see Particularity and Relation)
Particularity	An exclusive gateway can have one outgoing flow that is marked as the Default sequence flow . This is the flow of the process that will be followed if all other conditions do not match. The default flow is marked with a slash on the relation: You can mark a sequence flow as to be the default in the Attributes Panel:
Execution	None.
Editing and Styling	Refer to Working with the BPMN Editor for further information regarding editing of BPMN elements using the different context menus on the diagram pane. Refer to Styling BPMN Elements for further information regarding styling possibilities for BPMN elements, for example how to change the background color, the font style and size etc.
