SOAP Header with Envelope and Body is never sent to the client

Hi WSO2 I was very successful with following your example for creating data services like http://wso2.org/library/articles/introduction-php-data-services However what kind of service I create even doing a hello world service like described in the introduction the SOAP header with envelope body is always missing. I just get back straight XML like below. What do I miss that the SOAP header is not sent? This is what I get as a response. <?xml version="1.0"?> <myResponse>   <row>     <itemId>456</itemId>     <valid>0</valid>     <feedback>could not find parent_probe_id for probe_id</feedback>   </row> </myResponse> I would expect to get back a SOAP standard header like this incluing myResponse in the body? <?xml version="1.0"?> <soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> <soap:Body xmlns:m="http://www.example.org/myProject">   <myResponse>     <row>       <itemId>456</itemId>       <valid>0</valid>       <feedback>could not find parent_probe_id for probe_id</feedback>     </row>   </myResponse> </soap:Body> </soap:Envelope>
