Add attributes to XML tags in Yii 2 Response

Yii2. Action (method) in controller:

public function actionGet()
{
    Yii::$app->response->format = Response::FORMAT_XML;

    return [
        'items' => [
            ['id' => 'data'],
            ['id' => 'body'],
        ],
    ];
}

At output get XML:

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <items>
        <item>
            <id>data</id>
        </item>
        <item>
            <id>body</id>
        </item>
    </items>
</response>

How can add attributes in XML tags? And remove response tag:

<?xml version="1.0" encoding="UTF-8"?>
<items>
    <item update="true">
        <id>data</id>
    </item>
    <item update="false" new="true">
        <id>body</id>
    </item>
</items>
