      A "real" locale to be served by default (i.e. if the browser either
      doesn't have a requested locale, or it cannot be satisfied with any
      of the available locales).  The non-internationalized value "default"
      is actually deficient for any actual locale, so users should set this
      when then either <extend-property> or <define-property> user.agents for
      their available translations.  You should still have a locale named
      "default" (because various tools expect that to be valid), but it will
      be generated as the locale specified here.
