The LanguagePriority sets the precedence of language variants for the case where the client does not express a preference, when handling a MultiViews request. The list of MIME-lang are in order of decreasing preference. Example:
LanguagePriority en fr defoo.html, where
foo.html.fr and foo.html.de both existed, but
the browser did not express a language preference, then
foo.html.fr would be returned.
Note that this directive only has an effect if a 'best' language cannot be determined by any other means. Correctly implemented HTTP/1.1 requests will mean this directive has no effect.
