What about the case that you take the grammars from two different people? asking them to split their grammars regarding one's own conveniences won't be done. If one does split the grammars yourself then you have to repeat the step for every update again. I suppose it is simpler to be able to specify overrides explicitly - even if the root grammar simply specifies: s : B.s; > > > Also did you see my suggestion regarding CommonToken?

Still, setText isn't as convenient as the "!" syntax. Johannes -- Psssst! Schon vom neuen GMX MultiMessenger gehört?
