title: Transchoice and yaml in Symfony
body: <p>I'm convinced of the yml translation files in Symfony. The strings are well structured.</p>
  
  <p>My question is simple: is the following chaining in the plural string valid? And if the answer is yes, how to do that?</p>
  
  <pre><code>product:
      list:
          plural: "{0} product.list.none|{1} product.list.one|]1,19] product.list.lower20|[20,Inf[ product.list.larger20"
          none: There is no product
          one: There is one product
          lower20: There are %count% products
          larger20: There are many products          
  </code></pre>
