I agree with Joe's concerns on architecture and resouces. I imagine that best way to build a 4.0 processor is on top of a 3.0 processor and we don't have that out yet.
It might be possible to cherry-pick some 4.0 features on top of our 2.x code base like some new XPath functions for example, but I'm not sure that wouldn't be confusing for our users (but it might be helpful). I would like us to be in the position to release 2.x at will in a maintenance mode as we gear up for a 3.0, but that's just a personal preference.
