I don't find support for those datatypes compelling for XML.  I find them 
to be a distraction from the text-based functionality that makes XML so 
useful at best, a distressing calamity at worst.  I'm starting to argue 
that compromise even with the primitive types is a dangerous mistake.

I'm saying that:
* XML has a type system - it's called element types.
* Applications are welcome to build whatever processing they want on that 
* The "XML Core" should not recognize any type systems beyond those in XML 1.0.

Too minimalist for many? Probably.  Layering solutions rather than piling 
type systems into the core would take care of a lot of my 
objections.  Sadly, XQuery seems intent on building on XML+WXS, not XML.
