This ensures that only authenticated users will be able to make any web services calls, whether it be via web service import sets or inserting/deleting/querying via direct web services. This next step is very important if you are using .NET as a client to connect to ServiceNow. You must set the elementFormDefault property to false. This property defines how the WSDLs are qualified. Of course, if you do not consume our WSDL and just create the XML manually, then this property is irrelevant.
