Could you please also add a PHP example:

````php
<?php $view['blocks']->render(array(
    'name' => 'rssBlock',
), array(
    'title'    => 'Symfony2 CMF news',
    'url'      => 'http://cmf.symfony.com/news.rss',
    'maxItems' => 2,
)) ?>
````

(this example only works when the PRs referenced in #179  are merged)
