I will take a look on that. Probably we can implement some rules for
that if something is not defined.

Probably it works in some ues case but for sure not in all.
Let's give a sample. If you define a interface like
foo = zope.schema.Choice(
Then the foo.bar package must be available.
Another use case is if you use a product configuration like:
path = None
config = getProductConfiguration('p01.fsfile')
if config is not None:
path = config.get('fsstorage')
"You must define p01.fsfile 'fsstorage' for run this server")
The above sample needs to know about the fsstorage, otherwise you
will run into a ValueError during locale extraction which will abort
the extraction process.
The same is true for grok. If gork defines something in a module
which raises an exception if not available, it will run into an
error and abort.
I strongly recommend to use a real working setup if you extract
locales. The egg attribute supports such a setup.
The package attributes defines which package should get used
for deep into and extract from.
Note, it doesn't mean that every package must fail, but it's just
not what we should propose because it's not guaranteed that this
the sample in zaml.locales uses as egg zam.locales [extract]
which is a single line and uses the extra_requires from the
setup.py in zam.locales. In a poduction setup you whould never
use that extra_requires whihc should be fine.

The main goal is to have somethig for shared i18n message factories
like used in some z3c package and I guess others have in thier
custom projects. Of corse, if there is a way we should make it fit
for other use cases too.

Ok, will make progress on that next week. I let you know
if somehting is ready. I really appreciate your help and
comments and hope that we could make the recipe fit for
zope, z3c and grok.
