title: ParsleyJS - Localization with data-parsley-`constraint`-message
body: <p>Currently I'm using</p>
  
  <pre><code>data-parsley-`constraint`-message="English sentence goes here"
  </code></pre>
  
  <p>but now that I'm working to add localization these messages will never be translated using the i18n library because they are custom.</p>
  
  <p>Is there a way to add something like</p>
  
  <pre><code>data-parsley-`constraint`-message-fr="Francais francais francais"
  </code></pre>
  
  <p>or someway to do it through JS?</p>
  
  <p>Specifically I'm using data-parsley-required-message=""</p>
