My document is actually quite out of date (although I'm not sure I agree
with *exactly* how you have worded that).

When I was first doing this I was testing only with MSXML, which actually
allows what I have described (an xs:import with a @namespace value, to
import a schema with no @targetNamespace). However, when I later started
testing with other validators I discovered the error of my ways ;) and have
since taken a different approach (I have created 'proxy' schemas that allow
a chameleon schema to be imported into a host language using a different
namespace to that of the host language).

I've been working with Shane on getting some of these techniques into the
XML Schema Modularisation draft, so I haven't yet got round to updating the
Wiki--so apologies for that.
