XmlResponseFormatter settings can be specified in the application configuration, like so:

'components' => [
    'response' => [
        'formatters' => [
            'xml' => [
                'class' => '\yii\web\XmlResponseFormatter',
                'rootTag' => 'mytag'
            ]
        ],
    ],
],
