Doug Kaye points this out:
Don Box: Too Many Specs. The co-inventor of SOAP (now a Microsoft engineer) had harsh words this week for vendors contributing to the plethora of web-services specifications, and advised developers to read less of them and get on with writing applications.
Yes. I agree 100%. The WS-* specs seem to make things more confusing, more complicated, work against each other, and generally muck things up. I’ll bet that they don’t actually solve the problems that they set out to solve for most people.
