title: Symfony2 Translation Parameters inside config.yml(parameters.yml)
body: <p>I'm doing a web app, and I want to use parameters for translation files, like the parameters for twig, because I have some variables that I use in multiple translations.</p>
  
  <p>For example the site name. I already use Twig Global variables, but I also use the translator inside services, and I don't want to inject the container or the variables to these services.</p>
  
  <pre><code>twig:
      debug:            %kernel.debug%
      strict_variables: %kernel.debug%
      globals:
          sitename: %sitename%
          ....
  </code></pre>
  
  <p>Is something like that possible for translations?</p>
