Interceptor bindings need clarification

                 Key: CDI-186
                 URL: https://issues.jboss.org/browse/CDI-186
             Project: CDI Specification Issues
          Issue Type: Clarification
          Components: Interceptors
    Affects Versions: 1.1.EDR1
            Reporter: Jozef Hartinger
             Fix For: 1.1.EDR2

As part of CDI-2, changes were made to the Interceptors chapter of the CDI specification. These changes need further clarification:

Interceptor bindings defined on methods may override the interceptor bindings defined on classes.

One way to interpret this is that the set of interceptor bindings defined on a method overrides the set of interceptor bindings defined on a class, which is clearly not the intended behavior.

If the set of interceptor bindings of a bean
or interceptor, including bindings inherited from stereotypes and other 
interceptor bindings, has two instances of a certain interceptor binding type
and the instances have different values of some annotation member, the bean 
or interceptor must override the *inherited set* by definining an annotation 
instance of its own, otherwise, the container automatically detects the problem
and treats it as a definition error.

Here again I would avoid referencing "the inherited set", since it's not clear what that means, and rather use wording similar to the section 2.4.4 - default scope of a stereotype.
