Did you take a look at zope.app.i18nfile?

There is no need for different fields for supporting
i18n. I think adding i18n fields is a overhead.

We implemented allready i18n documents and local negotiator
in our projects.
Perhaps we move this after 3.1 to the trunk if somebody 
likes to have a generic i18n support.

I propose to improve this part after the 3.1 release
and implement one sample solution where most the time
will fit.

btw, we didn't improve the i18n part till now, because
there is no correct way where is THE solution.
Different usecses need different implementations.
But sure we can implement one concept in the core 
but this should be a simply way with no overhead.
