    <!--

    See the [documented coding standard](http://symfony.com/doc/current/contributing/code/standards.html)

    This CodeSniffer standard does not yet enforce the following:

    # Structure

    * Declare class properties before methods;
    * Declare public methods first, then protected ones and finally private ones.
    * Use namespaces for all classes;
    * Add PHPDoc blocks for all classes, methods, and functions;
    * The @package and @subpackage annotations are not used.
    * Use uppercase strings for constants with words separated with underscores

    # Naming Conventions

    * Use underscores for option, argument, parameter names;
    * Use Symfony as the first namespace level;
