I don't worry that much. I don't think it will happen very often that you
change
schema language for a particular application. And when it happens it is not by
accident so you will know to check for the use of the schema axis. I'ts a bit
like
changing datatype library in your RELAX NG schema.

Sounds like an interesting idea. What about abbreviation possiblities then?
I guess this approach excludes abbreviations from the extension axes or
should it be a part of the axis definition?
