Constitutionally incapable?

While I understand that RELAX NG _can_ support non-deterministic/unreliable 
models, I don't believe that makes it incapable of supporting reliable type 
assertions provided that the writers of the schema consider that a goal.

I've argued for a long while that type information should be 'painted' as a 
separate process from validation.  Compared to that approach, I can't say I 
find W3C XML Schema particularly reliable as a source of type assertions.
