Accessing an external web service causes Service Studio 3.1 to lock

I am trying to add a web reference to an external web reference

Whenever I try to add this web reference, it gives an error that an external validation error occured and then the service studio is locked up after displaying the feedback form box.

Q1: Why does service studio lock up for this?
Q2: Why can't I add the above reference URL as it is valid as per the W3C, although it is a lesser known variation.

Note that this web service is not document oriented, but is RPC oriented as defined at



What Service Studio version are you running? We tested with version, followed both feedback options ( "Send Feedback" and "Don't Send") and Service Studio doesn't lock up.

We analyzed this wsdl signature and detected that data type "anyType" is missing. We double checked this import in Visual Studio 2003 and the error is:
"E:\Work\Support\General Bugs\webreftest\Web References\\ Custom tool error: Unable to import WebService/Schema. Unable to import binding 'CDRAccessService_v2SoapBinding' from namespace ''. Unable to import operation 'getCallDetailRecordCountByFilter'. The datatype 'anyType' is missing."
