indicates if this execution represents an active path of execution. Executions are made inactive in the following situations:

• an execution enters a nested scope
• an execution is split up into multiple concurrent executions, then the parent is made inactive.
• an execution has arrived in a parallel gateway or join and that join has not yet activated/fired.
• an execution is ended.
