That wasn't the impression I got from Tom's comments; hopefully he'll
clarify. I really don't think OpenSSL actually does 'matching' kind of
work as is being described here.. It certainly shouldn't be deciding on
the validity of a certificate based on that. I wonder if this is
related to the question which was raised previously about if we trust
*intermediate CAs* when no root CA exists (which we certainly should
*not* be doing, but it's hardly clear what the heck happens when
everything has to go into a file called 'root.crt').

Thank you much for offering to write up the docs around this.
