Hello,

I’d like to pass some flags to my listener, but how I can extend my bpmn?

```
<startEvent id="start" flowable:async="true">
        <extensionElements>
            <flowable:executionListener event="start" class="bla.bla.DummyListener" />
        </extensionElements>
    </startEvent>

```

Thank you
