Does anybody have a clue about this one?

>> Unknown element {http://www.w3.org/2001/XMLSchema}simpleType.

It happens here:

require 'soap/wsdlDriver'
soap = SOAP::WSDLDriverFactory.new("test.wsdl")

the wsdl is fairly huge, I don't want to post it here unless 
somebody asks for it...

Best regards
