I don't think that this (ability to extend schema for your own purposes)
contradicts with existence of a normative schema.

You need schema for dozen of other things than validation. For example,
XML editors can be driven by schema to provide more comfortable data
entry to users.

Well, according to this logic, shouldn't be then proponents of HTML5
accused? ;-D

But it would be easier if they will define additional constraints on top
of schema validity then to duplicate work which can be easily expressed
using schemas.
