Er, OK. Bah, my webmail now blocks .xml as a dangerous attachment?!

Looks at:

Seems sound - 

I prefer to "assert" constraints and "report" interesting
valid content, but that's a style thing.

I wonder how many other constraints we can express in such as
schema, are we planning to make this schema normative to live 
alongside the XML Schema?

We could embed such co-constraints into the normative XML Schema,
but I much prefer to keep XPaths out of XML Schema documents 
as a "separation of concerns".
