not to come off as snide, but when was the last time the w3c simplified anything? I guess that would be xml version 1.0. Since then there have been sympathetic noises made as regards simplification of different standards, notably xpointer and xlink, but nothing I would call dramatic. Simplifying wsdl, that's dramatic! expect that if wsdl gets a working group it'll be a 400 page specification by the time it's done.
