+===== Notes =====
-Utilizing exclusive event-based gateway is a rather common mistake. What's missed in the diagram below is that the payment may arrive while we are discussing the issue with the client. If this happens, the message won't be catched and the process will hang on the gateway.
+  - Although it's usually better to use [[en:rule:collapsed_subprocess|collapsed representation of a subprocess]] to isolate its internals, it may make sence to depict the subprocess expanded in this technique to make the logic clear.
+  - As an exception to the [[en:rule:explicit_parallel_split|general rule]], one may initiate work and control flows directly from the start event:

-===== Notes =====
-Although it's usually better to depict subprocesses collapsed to isolate their internals, it may make sence to depict the subprocess expanded in this technique to make the logic clear.
-===== Exceptions =====
-Attached events are simpler and hence should be preferred in more straightforward scenarios.
