-----------------------------------------

That means that we have a big discussion on events for CDI 2.0, because the question becomes even worse if we introduce asynchronous events: CDI-31  ;)

> I would like to have the ability to stop event propagation after it is handled by any observer only for certain situations.  Is it possible to add a property to the annotation indicating whether the propagation should continue after being handled by the observer?  Alternatively, would it be more concise to add a qualifier annotation which specifies the propagation.
