I think that particular case -- selecting the language representation of the resource -- is better handled by the existing Accept-Language/Content-Language mechanism. The fragment addressing case that Silvia has suggested would be for more complex scenarios, such as a language learner explicitly selecting particular audio and subtitle tracks, or an editing application that needs to display/hide particular tracks during preview. cheers, Conrad.
