    Test the i18n directive.  First, we need to register the ZCML
    directive:

      >>> import zope.i18n
      >>> from Products.Five import zcml
      >>> zcml.load_config('meta.zcml', zope.i18n)

    Let's register the gettext locales using the ZCML directive:

      >>> configure_zcml = '''
      ... <configure xmlns="http://namespaces.zope.org/zope"
      ...            xmlns:i18n="http://namespaces.zope.org/i18n"
      ...            package="Products.Five.tests">
      ...   <i18n:registerTranslations directory="locales" />
      ... </configure>'''
      >>> zcml.load_string(configure_zcml)

    Now, take an arbitrary message id from that domain:

      >>> from zope.i18nmessageid import MessageFactory
      >>> from zope.i18n import translate
      >>> _ = MessageFactory('fivetest')
      >>> msg = _(u'explicit-msg', u'This is an explicit message')

    As you can see, both the default functionality and translation to
    German work:

      >>> translate(msg)
      u'This is an explicit message'
      >>> translate(msg, target_language='de')
      u'Dies ist eine explizite Nachricht'
