It's a work in progress.  Makoto and Kohsuke and others are thinking about
exactly what works and what doesn't.

Validation is validation, type inference is type inference.  As I posted
a moment ago, someone could write an RNG-based type inferencer for simple
types today (maybe even make it output the input, decorated with xsi:type
