PEAR:Config writes wrong XML

I'm trying out the PEAR:Config module with the given examples. I modified the example to write XML rather than phparry to disk. Looks like this: <?php // initialize a Config_Container object

       require_once('Config.php');
       $conf =& new Config_Container('section', 'conf');
       $conf_DB =& $conf->createSection('DB');
       $conf_DB->createDirective('type', 'mysql');
       $conf_DB->createDirective('host', 'localhost');
       $conf_DB->createDirective('user', 'root');
       $conf_DB->createDirective('pass', 'root');

       // set this container as our root container child in Config

       $config = new Config();
       $config->setRoot($conf);

       // write the container to a php array
             $config->writeConfig('config/configuration.xml', 'xml',
                           array('name' => 'config'));

       // print the content of our conf section to screen
             echo $conf->toString('xml', array('name' => 'test'));

?> This produces this: <?xml version="1.0" encoding="ISO-8859-1"?> <config> <?xml version="1.0" encoding="ISO-8859-1"?> <config> <DB>

     <type>mysql</type>
     <host>localhost</host>
     <user>root</user>
     <pass>root</pass>

</DB> </config> </config> So I wonder if this is just a fault of mine or if there is some bug inside the writer that one could fix. Thanx for any help, Alexander
