Pre-caffeine, I couldn't think of the attribute for holding CNAMEs,
thank you.  Path validation, I think requires both, but if a CNAME
shows up in subjectAltName, and everything else checks out, you are
good to go.  I think (pretty sure) validation requires a check first
for CN though, then it goes through the alternate names.  RFC5280
hasn't changed or is there an update I missed that changes proper path
validation?  I would guess things would break without CN values
included.  Anyway, I think we are good on this one now.

Thanks,
Kathleen
