actually, now that I think about it, validation of NAPTR could 
be very tricky.  the reason is that with NAPTR records, the
label of the record doesn't necessarily have to have anything 
to do with the name being referred - you could start out looking
for keys for a resource name like http://www.ietf.org/foo/bar/ and 
end up having to get NAPTR records for completely unrelated domains
(like http.uri.org) in order to know how to parse that resource
name...and the domains to which you get referred to look up the
actual keys (depending on the format of the resource name and
how it's delegated) might have nothing at all to do with ietf.org.

(this was actually considered a desirable feature for URN resolution -
the party that defines a name and binds it to a resource, isn't 
necessarily the same one that provides the information about it -
especially if a significant length of time has passed since the
name was created and bound.)
