I know zip about EDIFACT, but your following comments about encoding '@'
and whatnot seem a bit weird to me.  A BER-encoded Certificate is already
a very weird binary object that will need something like base64 (which
supposedly would get through Telex machines fine).  Whether '@' is used or
not is irrelevant once the base64 wrapper has been added.  I've probably
missed something though, so forgive this tired Aussie if that is the case. 

I do find it strange that Internet WWW culture accepts such as

"URL: gopher://naic.nasa.gov:70/00/Notice";

as acceptable to users as a resource reference string,

but the Internet-types will no doubt scream at the equally machine-oriented

"To: /S=williams/OU=Sterling/O=ARC/PRMD=NASA/ADMD=TELEMAIL/C=US/ at 
sprint.com"

or 

"To: /S=williams/OU=Sterling/O=ARC/PRMD=NASA/ at arc.nasa.gov"

The X.400 forms are unnecessarily verbose and include unnecessary routing 
instructions (ADMD=TELEMAIL).  IMHO of course.
