RFC 4945 states that implementations SHOULD NOT send CERTREQs for types 7
and 8.  If they are sent then an implementation MUST NOT require the
recipient to respond and the recipient MAY ignore the request.  Given that
I don't expect that it is common that implementations send CERTREQs with
type 7 or 8 to begin with.  If they do I agree with Tero that an empty
certificate authority field is probably sufficient.


OTOH, I would not be opposed to adding RFC 4945's "SHOULD NOT send CERTREQs
for type 7 and 8" statement here.


> OTOH, this allows type 10, which is unspecified and should be removed.
