===== Примечания =====

Хотя спецификация BPMN 2.0 не запрещает несвязные потоки управления в рамках одного пула, это плохая практика.

У процесса может быть больше одного начального и больше одного конечного события, но все они должны быть связаны потокам управления в единый поток работ.

Подпроцесс "параллельный блок" ("как не надо", внизу) лучше не использовать, а явно показывать параллельное расхождение и схождение ("как надо", внизу).
