 methods control `output buffering`_ which allows you to "trap" the echoed
 output of ``$server->handle()``. This is necessary because Symfony expects
 your controller to return a ``Response`` object with the output as its "content".
-You must also remember to set the ``"Content-Type"`` header to ``"text/xml"``, as

 Below is an example of calling the service using a native `SoapClient`_ client. This example
 assumes that the ``index()`` method in the controller above is accessible via
