Description:
------------
I'm trying to access a web service using a .wsdl file, literal 
style. The wsdl defines two schemata with different namespaces 
where the first one refers to the latter. The message 
parameter in the SOAP envelope gets the wrong namespace.

Reproduce code:
---------------
The wsdl contains two schemata:

    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl" xmlns:xi0="http://targetNS" xmlns:xi1="http://otherNS" targetNamespace="http://targetNS">
      <xsd:import namespace="http://otherNS"/>
      <xsd:element name="EmployeeBasicDataByEmployeeQuery" type="xi1:EmployeeBasicDataByEmployeeQueryMessage"/>
      ...
    </xsd:schema>
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl" xmlns:xi0="http://targetNS" xmlns:xi1="http://otherNS" xmlns="http://otherNS" targetNamespace="http://otherNS">
   <xsd:complexType name="EmployeeBasicDataByEmployeeQueryMessage">
        <xsd:sequence>
          <xsd:element name="EmployeeBasicDataSelectionByEmployee">
      ...
    </xsd:schema>

The calling PHP code:
$res = $soap->EmployeeBasicDataByEmployeeQueryResponse_In(
    array("EmployeeBasicDataSelectionByEmployee" => array("EmployeeID" => 10))));
echo $soap->__getLastRequest() . "\n";

I also tried classmaps and various array combinations. If you add another array level (EmployeeBasicDataByEmployeeQuery) the above gives an error (object hasn't 'EmployeeBasicDataSelectionByEmployee' property).

Expected result:
----------------
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/
soap/envelope/"
  xmlns:ns1="http://targetNS"
  xmlns:ns2="http://otherNS">
  <SOAP-ENV:Body>
    <ns1:EmployeeBasicDataByEmployeeQuery>
      <ns2:EmployeeBasicDataSelectionByEmployee>
        <ns2:EmployeeID>10</ns2:EmployeeID>
      </ns2:EmployeeBasicDataSelectionByEmployee>
    </ns1:EmployeeBasicDataByEmployeeQuery>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Actual result:
--------------
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/
soap/envelope/"
  xmlns:ns1="http://my/namespace/somewhere">
  <SOAP-ENV:Body>
    <ns1:EmployeeBasicDataByEmployeeQuery>
      <EmployeeBasicDataSelectionByEmployee>
        <EmployeeID>10</EmployeeID>
      </EmployeeBasicDataSelectionByEmployee>
    </ns1:EmployeeBasicDataByEmployeeQuery>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
