I agree.

I would say trying to change AS to support RELAX NG will be a complete
rewrite of the spec. For example, they assume that every element
declaration has a name.


In my experience, if you want to be abstract enough, you cannot be more
concrete than the Acceptor model of MSV (com.sun.msv.verifier.Acceptor).
This is so abstract that it's pretty useless for anything but validation.
Yet this is not abstract enough to support Schematron.

One can try to abstract validation as a function of a document and a
schema:

function validation( schema, document ) : boolean

But this doesn't capture the infoset augmentation aspect of many schema
languages.
