Re: mule-axis.xsd causing Unique Particle Attribution violation
My suggestion is the outdated XML parsers. Can you check what's in your endorsed Mule's folders and/or JRE's one? (need a list of libraries). Are you running standalone? Which JDK?
The problem could be that e.g. Eclipse might be using an older xml parser OOTB. This has to be done, of course, after you jump to 2.0.0 final, there were many updates to schemas in between.
