Probably true. On the other hand, considerable experience has been
gained with X.509 certificates, so not dismissing them out of hand is a
Note that the "DN problem" can be avoided rather simply: in X.509
certificates the Issuer and Subject names must be of type Name, where
Name is defined in X.501; in X.501, Name is defined as a CHOICE type,
with the choice currently limited to rdnSequence.
There is nothing that prevents interested parties from extending the
choice for experimental purposes, veriyfing that the choice is useful,
then petitioning the ITU/ISO to formally add the new element to the
CHOICE. (I've been thinking about this approach and how it could be
