Ok so I moved configuration to the persistence block and try to update every think based on Configuration.php

I reordered the parameter to fit to Configuration.php


but I did'nt really get on to convert the multilang > locales part, can you tell me how to do it please ?

And by the way I have two question on this : 

- is it normal to set the attribute name with '-' if they are with '_' in Configuration.php ?
- is it normal that this url is a 404 : http://cmf.symfony.com/schema/dic/block ?
