title: Symfony 2 translation: why XLIFF?
body: <p>Here:</p>
  
  <p><a href="http://symfony.com/doc/current/book/translation.html">http://symfony.com/doc/current/book/translation.html</a> they explain that XLIFF is the preferred way for translation, but they dont explain <em>why</em>. I personally think YML is easier, so I'm wondering why XLIFF is better (and it seems it's only here that it's better).</p>
  
  <p>Any idea?</p>
