    // An HTTP SOAP request is an HTTP request where the SOAP XML composes the body.
    // This example demonstrates how to add a WS-Security header such as the following:
    // 
    // <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
    //   <wsse:Username>user</wsse:Username>
    //   <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
    //   <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
    //   <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
    // </wsse:UsernameToken>
    // 

    // First build some simple SOAP XML that has some header and body.
    CkXml xml = new CkXml();
    xml.put_Tag("env:Envelope");
    xml.AddAttribute("xmlns:env","http://www.w3.org/2003/05/soap-envelope");

    xml.UpdateChildContent("env:Header|n:alertcontrol|n:expires","2001-06-22T14:00:00-05:00");
    xml.UpdateAttrAt("env:Body|m:alert",true,"xmlns:m","http://example.org/alert");
    xml.UpdateChildContent("env:Body|m:alert|m:msg","Pick up Mary at school at 2pm");
    Log.i(TAG, xml.getXml());
    Log.i(TAG, "----");

    // The following SOAP XML is built:

    // 	<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
    // 	 <env:Header>
    // 	  <n:alertcontrol xmlns:n="http://example.org/alertcontrol">
    // 	   <n:priority>1</n:priority>
    // 	   <n:expires>2001-06-22T14:00:00-05:00</n:expires>
    // 	  </n:alertcontrol>

    // 	 </env:Body>
    // 	</env:Envelope>
    // 

    // Now build the WSSE XML housing that we'll insert into the above SOAP XML at the end.
