Problems with WSDL generation in 60

Hey everyone, new to this forum… we are thinking about upgrading to IS 6.0 in the near future. One feature that we’d like to take advantage of is the WSDL generation ability. I created a very simple flow service, created the output schema, and generated the WSDL, but it failed to load in my XML editor (XMLSpy) and .net failed when I tried create a client proxy to the service. Something wrong with the namespaces. I can correct it by hand and get it to work, but this is somewhat cumbersome. Is this a known bug?
thanks
