Mozilla SOAPCall, Serializing and Deserializing parameters

Hi
I writing a basic SOAP application using Mozilla at the client side and 
MS IIS at the server side running a .NET webservice. It's ok to use the 
SOAPCall class for simple parameter type (string, number, ...). With 
complex types (struct, array, ...) the encoding process is ok but when 
deserializing the SOAP response with complex return value type from the 
server, SOAPCall seems to do an invalid process by discarding all the 
href attributes. I may be wrong but could anyone show me how to get the 
result deserialized crrectly in javascript

Thanks in advance
