+Use a subprocess containing the control branch to implement versatile event processing logic.
+===== ✔ How to =====
-Use a subprocess to watch event(s) while executing a series of activities.
+Let's assume that we need to obtain payment from the client, watch the payment due date and talk with the customer in case of delay. Use the following technique:
-===== ✔ How to =====
+  - Put the "Obtain payment" task into subprocess.
+  - Start the subprocess with the parallel gateway followed by two branches, "working" and "control".
+  - Put the "Obtain payment" at the working branch.
+  - Put the timer at the control branch.
+  - End both the working and control branch with the terminate event.

+  - 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:
