[Zope-dev] Lazy translation domains

In 2008, the `zope_i18n_allowed_languages` environment setting was introduced to limit the languages for which a message catalog is loaded when you register translations using the "registerTranslation" ZCML directive, and to be able to negotiate a list from a list of available languages. This branch implements a fallback mechanism where: 1) the allowed languages are determined at runtime. 2) translation domains are lazy, and load message catalogs only when required. http://svn.zope.org/zope.i18n/branches/lazy-tds/ \malthe
