Description Jari Bakken 2011-04-09 15:07:25 UTC 
It's sometimes useful to define a hierarchy of exceptions, e.g.

    exception NotFoundException { };
    exception NoSuchElementException : NotFoundException { };
    exception NoSuchFrameException : NotFoundException { };

If not, then the section on Exceptions (3.4.) should include this as another way exceptions differ from interfaces.

Yes, we discussed something like this recently on the mailing list:

I plan to add this to the spec soon.
