> The validation of enabled interceptors, alternatives and decorators is currently tightly related to the beans.xml file, e.g.:
> {quote}If the same class is listed twice under the <interceptors> element, the container automatically detects the problem and treats it as a deployment problem.{quote}
> With CDI-97 in place, which allows extensions to change the enabled alternatives, decorators and interceptors, this is no longer sufficient. IMO, the validation of enabled interceptors and decorators should be the following:
> 1.) For each deployment descriptor, the container verifies that it does not contain duplicate interceptors, decorators or alternatives.
> 2.) For each BDA, the container fires the ProcessModule event allowing extensions to modify enabled alternatives, interceptors and decorators.
> 3.) For each BDA, the container verifies that the resulting collection of enabled alternatives, decorators and interceptors does not contain duplicates.
> The step 1.) is not actually necessary but may be convenient.
