I'm in favour of (2) as well. The question then is, should the spell
checker be the morphological analyser used as input to the grammar
checker, or should it be another file? So far we have:

1) Descriptive morphological analyser
2) Disambiguation file 
3) Grammar checker rule file
4) Suggestion file
5) Some kind of index/manifest

Should we add 'normative acceptor' to that ?
