Does anybody know a source ofdocumentation/examples about the Testdirector VAPI-XP scripting for Web Services?

I have to test a WS using a complex XML type defined by a proper XML schema

TD generates a sript like the one below but then fails running because Item is a complex type. Is there a way to define complex type serialization or to invoke the WS passing the XML request as a string?

soapBLS = new ActiveXObject("MSSOAP.SoapClient30");
result = soapBLS.getStatus(Item);
</pre><hr />
