Need namespace declaration in SOAP Envelope

Issue

• The location of our namespace prefix name changes during execution of service, but namespace values are same. The SOAP response does not have the namespace prefixes/values at the envelope level and all namespace values are in-lined in the response body. We need it in the Envelope because we have a stylesheet which expects to see it there. How can we solve this?

• Response (actual):

  <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
     <soapenv:Header/>
     <soapenv:Body>
        <ns2:locateBenefits xmlns:ns2="http://www.somecompany.com/benefits/"/>
     </soapenv:Body>
  </soapenv:Envelope>
  

• Response (desired):

  <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns2="http://www.somecompany.com/benefits/">
     <soapenv:Header/>
     <soapenv:Body>
        <ns2:locateBenefits/>
     </soapenv:Body>
  </soapenv:Envelope>
