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.
