Agreed.

I'm not sure what you mean here. I was simply saying that I hadn't had the same inference you had from Jozef's comment.

> I already published a few examples for @Specializes, @Alternatives and could easily add @Decorator and @Interceptor examples. All show 1.(b) behaviour on Weld, GlassFish, JBossAS, etc. I'm still missing a single example where it's a clear 1.(a) in an EAR scenario.. 

Sure, the more examples we have the better! 

I'll check with Jozef exactly where Weld does and doesn't follow the 1(a) behavior tomorrow, so that I'm not just speculating.
