I think we should do the translation in either case.  But the translation
for a string or a id with an unknown domain should just return the original,
with interpolation, if necessary.  Perhaps we should have a warning in
dev mode.  We should also think about how development tools can be used to
help with this. The test language support I checked in yesterday should
help, I think.

What is Zope-3.1 behavior?

This example is particularly agregious.  Still, I think your fix is necessary.
I think we need better tools for checking i18n and l10n.
