I am personally still unconvinced that this is the right way to go and
still convinced that other more efficient ways of "binding" XML and
Object can be found either through "untyped bindings" like TreeBind, UML
modelling that generates both code and schemas from a single model or
code annotation. 

(That was one of James Clark messages at XML 2001 and I think his talk
was really visionary.)

Can you elaborate why the fact that RELAX NG uses W3C XML Schema Part 2
as its more popular datatype library is a problem for data binding?
