Yes, agreed. I'm trying to take this by small steps as it's a working
architecture, but one of my goals is to make at least human-readable
attributes text node content instead. Another goal is to try to make
overrides of existing definitions more minimal than just copying them
all and making changes. :)

Thanks! If you want to use any of this stuff as test cases let me know
and I'll work it out with the Zope 3 developers. It's under a BSD-ish 
license but I'm sure no one will mind allowing you to relicense this
tidbit.

I'm vaguely wondering if (and how) it can be used to do a data-binding
language or something along those lines. Or help informing a
structured XML editor. i.e. using the schema for more than just
validation.

I know there's a lot of work in those areas for 
W3C XML Schema, and I'm wondering whether there's something inherent in 
Relax NG that would make this harder, or that it's just that I haven't
found the people yet who are doing this. :)
