It means that we'd need to forego the idea that installing zope.i18n by itself would get us any ZCML support. Alternately, we talked on IRC about splitting this package up into one that had no ZCML and one that had ZCML and dependencies on the ZCML processing machinery, but I suggest that that's a "Zope 3.5" sort of thing, and we should try to fix these dependencies in a 3.4 version bump without splitting packages via paring down "install_requires" vs. "tests_require". - C
