WCF SOAP service that changes the name of the elements of an array element during (de) serialization

Question

I have a client (which is not very flexible in sending SOAP) that generates SOAP similar to the following from a method with signature void Test(int[] test):

<?xml version="1.0" encoding="UTF-8" ?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <SOAP:Body>
        <Test xmlns="http://www.mydomain.com/">
            <test>
                <item>1</item>
                <item>2</item>
                <item>3</item>
                <item>4</item>
                <item>5</item>
                <item>7</item>
            </test>
        </Test>
    </SOAP:Body>
</SOAP:Envelope>

I need my WCF SOAP web service to deserialize this correctly.

By default, it throws the following exception:

System.ServiceModel.Dispatcher.NetDispatcherFaultException: The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'Test'. End element 'test' from namespace 'http://www.mydomain.com/' expected. Found element 'item' from namespace 'http://www.mydomain.com/'. Line 6, position 7. ---> System.Xml.XmlException: End element 'test' from namespace 'http://www.mydomain.com/' expected. Found element 'item' from namespace 'http://www.mydomain.com/'.

If you add an attribute XmlSerializerFormatto the service interface, an exception will not be thrown, but the resulting array is empty (I suspect that it does not recognize the individual elements of the array properly).

If you add an attribute XmlArrayItemto the parameter, it will not change anything ( void Test([XmlArrayItem("item")] int[] test);in the service).

I tried various other combinations XmlSerializerFormat, XmlArrayItemand XmlArray, with no luck.

[CollectionDataContract(ItemName = "item", Namespace = "http://www.mydomain.com/")]
public class ClientArray<T> : List<T> {

}

void Test(ClientArray<int> test);
