title: Symfony2 Route global {_locale} requirements
body: <p>I have in my routing.yml specified the parameter _locale requirements in every single route and I think that must be something to simplify this situation.</p>
  
  <p>routing.yml</p>
  
  <pre><code>ProjectBaseBundle_index:
      pattern:  /{_locale}
      defaults: { _controller: ProjectBaseBundle:Default:index }
      requirements:
          _locale: en|es
  
  ProjectBaseBundle_privacy:
      pattern:  /privacy/{_locale}
      defaults: { _controller: ProjectBaseBundle:Default:privacy }
      requirements:
          _locale: en|es
  
  .....
  
  ProjectBaseBundle_legal:
      pattern:  /legal/{_locale}
      defaults: { _controller: ProjectBaseBundle:Default:legal }
      requirements:
          _locale: en|es
  </code></pre>
  
  <p>I am using Symfony2.1 beta 3</p>
  
  <p><strong>Is possible to specify a global _locale requirements for all my routes?</strong></p>
