It allows splitting of compound transitions into multiple alternative paths such that the decision on which path to take may depend on the results of Behavior executions performed ... Full quote If more than one guard evaluates to true, one of the corresponding Transitions is selected. The algorithm for making this selection is not defined. Next snippet choice – ...
