Indeed, I think it is very useful. Without it schema maintenance would
be more pain.

What is the current situation. Are they manually synchronized with XSDs
or are they generated automatically? I think that goal should be to
generate them automatically from XSDs (or vice versa). Although it would
require adding more annotations to schema -- for example to handle
recent (r|ref) change in RELAX NG schemas only.

The real question now is to whether I should learn F# or Scala. ;-D
