Php 使用soap客户端类映射函数时缺少命名空间前缀

嗨，我遇到了一些奇怪的错误，类似于这个非常旧的PHP错误：

唯一的区别是：我使用的是php的soap客户端的classmap函数

看起来像这样：

class Client extends \SoapClient
{
//left something out here
const DOMAIN_MODEL_NAMESPACE = 'Domain\\Model\\';


/**
 * @return array
 */
private function getClassmap()
{
    return array(
        'AddressCheck' => self::DOMAIN_MODEL_NAMESPACE . 'AddressCheck\\AddressCheckRequest',
        'AddressCheckResponse' => self::DOMAIN_MODEL_NAMESPACE . 'AddressCheck\\AddressCheckResponse',
        'matchingAddresses' => self::DOMAIN_MODEL_NAMESPACE . 'AddressCheck\\MatchingAddresses',
        'address' => self::DOMAIN_MODEL_NAMESPACE . 'Common\\Address',
        'RequestHeader' => self::DOMAIN_MODEL_NAMESPACE . 'Common\\Header\\RequestHeader',
        'salesOrderEntry' => self::DOMAIN_MODEL_NAMESPACE . 'Common\\Header\\SalesOrderEntry'
    );
}

/**
 * @param Configuration\ConfigurationInterface $configuration
 * @param string $wsdl
 */
public function __construct($wsdl, Configuration\ConfigurationInterface $configuration)
{
    $options = array(
        'classmap' => $this->getClassmap(),
        'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
        'location' => $configuration->getServiceLocation(),
        'trace' => 1,
        'soap_version' => SOAP_1_1,
        'exceptions' => 1,
        'cache_wsdl' => 0
    );
    parent::__construct($wsdl, $options);
}
}

其他类别：

$address = new Common\Address($street, $houseNumber, $postalCode, $city);
$request = new AddressCheck\AddressCheckRequest($address);
$response = $this->soapClient->__soapCall($requestName, array($request));

这是由PSR-4自动加载生成的，但随后进行了一些修改以适应PSR-4自动加载

我的问题在于生成的XML请求：

应该是（由SOAPUi生成！）： ->看起来像肥皂。（对吗？）
