[IETF-PKIX] Question about SubjectAltNames

["Jim Schaad (Exchange)" <jimsch@xxxxxxxxxxxxxxxxxxxxxx>]

I have a situation where the subject DN for a certificate does not
contain a good displayable name for the person that the certificate is
issued for. I would put a displayable name of some type in the
subjectAltName field, but cannot figure out how this should work.  This
is no such thing as a Universial Name field in the GeneralName
structure.  Is the correct way to go about this to create an x500Address
with a cn field? or somthing else?  I've looked in serveral places and
cannot figure this out.  I would expect due to the uniqueness of a
Subject DN that this problem may crop up in more that one context.  Is
this something that needs to be addressed in the PKIX documents?
