Десериализация xml в объект в Symfony 4.4.30 с помощью компонента Symfony\Component\Serializer\Serializer

задача: денормализовать xml ответа от https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml в объект с использованием компонента Symfony\Component\Serializer\Serializer

Хочу получить такой объект: `

App\Model\EcbHttpResponse\Envelope Object
(
    [subject:protected] =>
    [Sender:protected] =>
    [Cube:protected] => App\Model\EcbHttpResponse\CubeOuter Object
        (
            [Cube:protected] => App\Model\EcbHttpResponse\CubeInner Object
                (
                    Array
                    (
                    [0] => App\Model\EcbHttpResponse\Cube Object ([currency:protected] => 'USD' ),
                    [1] => App\Model\EcbHttpResponse\Cube Object ([currency:protected] => 'JPY' ),
                    )

                )

        )

)

`

а вместо этого получаю: `

App\Model\EcbHttpResponse\Envelope Object
(
    [subject:protected] =>
    [Sender:protected] =>
    [Cube:protected] => App\Model\EcbHttpResponse\CubeOuter Object
        (
            [Cube:protected] => App\Model\EcbHttpResponse\CubeInner Object
                (
                    [Cube:protected] => Array
                        (
                            [0] => Array
                                (
                                    [@currency] => USD
                                    [@rate] => 1.1617
                                    [#] =>
                                )

                            [1] => Array
                                (
                                    [@currency] => JPY
                                    [@rate] => 132
                                    [#] =>
                                )

                        )

                )

        )

)

`
