 The exclusive (XOR) and inclusive (OR) gateways for splitting a process flow are supported.
 
 The conditions are part of the outgoing sequence flows inside a `conditionExpression`.
-The condition needs to be single-line JavaScript code (see [Script Tasks](bpmn-script-task) which evaluates to a boolean.
-On the engine, the code is taken and a `return` is put in front of it to get the result.
-An outgoing sequence flow is only allowed to have _no_ condition, if the `default` attribute inside the gateway element is pointing to this sequence flow.
+The condition needs to be single-line JavaScript code (see [Script Tasks](bpmn-script-task)) which evaluates to a boolean. In difference to Script Tasks, it is not necessary to use `variable.get()`. All process variables are directly accessable, e.g. `cost > 500`.
