Regrets from me again, I'm at a conference this week. I saw one item I
wanted to comment on...

That isn't a correctly implemented validator. XSD generally binds a schema
document to a single target namespace (ignoring chameleon schemas), so by
definition any time there are multiple namespaces in a document, you'll have
multiple XSD instances.

(It's certainly true that the most broken aspect of most parsers/validators
is their mechanism for acquiring schemas, but it's a requirement of all
implementations to do so safely somehow.)
