How to pass complex type to SOAP service?

Question

PHP

Hello!
I'm setting up interaction with a third-party service and I can't correctly pass parameters to it. The service gives errors about incorrect parameter.
Here is a piece of the WSDL document

<?xml version="1.0" encoding="UTF-8"?>

            <soap12bind:address location="http://location.ru"/>
        </port>
    </service>

</definitions>

and php code to execute the method

try {
    $client = new SoapClient("http://service.wsdl", [
            'login' => $login,
            'password' => $password,
            'soap_version' => SOAP_1_2,
            'cache_wsdl' => WSDL_CACHE_NONE,
            'trace' => true,
            'features' => SOAP_USE_XSI_ARRAY_TYPE,
            'use'      => SOAP_LITERAL
        ]);
    $param = [
        "Parameters" => [
            "TypeRequest" => "DocumentRequest",
            "TypeSelect" => "Changed",
            "ExecutionDate" => "2019-12-15",
        ]
    ];
    $result = $client->GetData($param);

} catch (Exception $e) {
    echo $e->getMessage();
}

Swears at the incorrectness of the "TypeSelect" parameter. I so understand that I incorrectly transfer it.
How to pass complex SOAP types to a service in general?

Tried:

$param = [
        "Parameters" => [
            "TypeRequest" => "DocumentRequest",
            "TypeSelect" =>[ 
                "Changed"
             ],
            "ExecutionDate" => "2019-12-15",
        ]
    ];
