Xml WCF SOAP-从子节点删除命名空间

我正在构建一个服务，并且有一个客户机，它需要一种特定格式的xml，我正试图在soap服务中接收这种xml。我遇到的问题是，当我需要名称空间前缀仅位于根节点上时，它将应用于子节点。下面是为soapui中的请求生成的soap信封：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:contact.com">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:ContactNotification>
         <!--Optional:-->
         <urn:Identifier>
            <!--Optional:-->
            <ID>122</ID>
         </urn:Identifier>
         <!--Optional:-->
         <urn:Details>
            <!--Optional:-->
            <ContactPerson>c</ContactPerson>
         </urn:Details>
      </urn:ContactNotification>
   </soapenv:Body>
</soapenv:Envelope>

已经四处寻找，但找不到解决方案。

您是否曾设法找到解决方案？

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:contact.com">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:ContactNotification>
         <!--Optional:-->
         <Identifier>
            <!--Optional:-->
            <ID>122</ID>
         </Identifier>
         <!--Optional:-->
         <Details>
            <!--Optional:-->
            <ContactPerson>c</ContactPerson>
         </Details>
      </urn:ContactNotification>
   </soapenv:Body>
</soapenv:Envelope>
