As far as it is feasible the IETF "richmail" project is being
pushed to use as simple a subset of SGML as possible so that people
can type it in by hand and not have it distract too much from the
actual text.

   However if a suitable SGML document type HAS been defined for your
   purposes then you ought to publish it and reference it as a public
   text. Then you can use a MUCH less verbose (but equally readable)
   notation - e.g. omitting or shortening most of the end markers and
   making use of various abbreviations and typist techniques.

There's good reasons not to use the SGML minimization rules, not the
least of which is to minimize the amount of work that "dumb" user
agents have to do to strip out the formatting information.  To quote
from the internet draft --
<excerpt>
            NOTE ON THE RELATIONSHIP OF RICHTEXT TO SGML:   Richtext  is
            decidedly  not  SGML,  and  should  not be used to transport
            arbitrary SGML  documents.   Those  who  wish  to  use  SGML
            document  types  as  a mail transport format should define a
            new text-plus subtype,  e.g.  "text-plus/sgml-dtd-whatever".
            Richtext  is  designed  to  be  compatible  with  SGML,  and
            specifically so  that  it  will  be  possible  to  define  a
            richtext  DTD  if  that  is  desired. However, this does not
            imply that arbitrary SGML can be called richtext,  nor  that
            richtext  implementors have any need to understand SGML; the
            description  in  this  memo  is  a  complete  definition  of
            richtext.						
</excerpt>
The approach of avoiding the complicated minimization rules
facilitates treatment of the text by more general systems, such as
Open Text System's PAT, which can be taught to recognize very simple
tagging schemes but which don't have facilities for disambiguating
whether a minimized end-tag matches one or more begin-tags.  I also
hope to have a system built in GNU Emacs, and while the richtext
scheme seems easy enough with it I don't have any intention of hacking
full-blown SGML in emacs.

As an extreme example, all of the markup in this document is one tag
per line, which is extremely easy to wipe out with even with grep -v.

By the way, Ed, I think you may be the first person in the history of
the world to successfully send a multifont email message to someone who
wasn't using the same software with which the message was composed.
Congratulations!	nsb@thumper.bellcore.com
