John Ament commented on CDI-611:
--------------------------------

The fact that event qualifiers and bean qualifiers don't work the same way is still an issue for a number of developers I've worked with.

> While the current spec is in fact correct, it is quite hard to decipher what it is actually trying to convey. 
> Elsewhere in the spec, we talk about subsets of qualifiers while here we don't. There is a code sample and a sentence saying *"Then this observer method will only be notified if all the observed event qualifiers are specified when the event is fired:"*
> This can be interpreted as:
> * _"I must fire an event with exactly the same qualifiers as this observer has in order to notify it"_ (*wrong assumption* - it can have more qualifiers)
> * _"I must fire an event which will contain at least the same qualifiers as this observer has in order to notify it"_ (*correct* - yet not so obvious)
> I will try to come up with some improvement to make this clear. As it is, it always takes me several reading to soak it in.
