Description: In my last column I sketched out an alternative to WSDL. In my ongoing attempts to suggest useful ideas for others to implement, I now want to spend some time discussing an implementation of a real service. I\'m going to look at XKMS, the XML Key Management Service. (A separate document specifies bindings to SOAP and HTTP.) This is a recommendation that has finished its W3C Last Call phase and is unlikely to see anything other than editorial changes at this point.
