Why would you hate to see, or have to maintain such a schema? Is it the
additional tedium you find uninspiring? Or do you think it is a bad
application, or even an abuse of XML Schema? If it is the latter, could
you explain why you think this is bad?

That's a good idea. Strangely, it hasn't occurred to me I could use XSLT
for the job. It doesn't seem to have a reputation for being a validator
tool, yet.

Thank you very much!
