Coregions on Sequence diagram
Coregions are used when the sequence of events does not matter – they can occur safely in any order.
The Coregion symbol is available on the Draw toolbar of the Sequence diagram of SysML and UML 2.5. It can be placed on a Lifeline over the messages that act in parallel.
