one thing erik and I debated when doing the doc fixup was to include some
tags about whether attrs were
-optional
-required
-required if some other attr was present/absent
-one of a choice allowed

I think RNG has much better support for saying 'attr a is allowed only if
attr b is absent/present', which makes it good for ant.

I'll be saying some bad things about Schema at the Portland .net users group
(web services section) on october 5, [next to some bad things about WSDL,
JAX-RPC, Java support of unsigned datatypes and .NET's lack of support of
Soap with Attachments]. All welcome, anyone who anything to do with the
design of any of the above extra welcome. www.padnug.org.
