We debated the issue of  uucp and bitnet PRMD and/or
the solution of DD.BITNET DD.UUCP (similar to DD.RFC-822)
and finaly for the simp0licity it gives on the user side
we decided in France to only have one* SDA set and one DDA type

	C=FR; A=red; P=internet;
	with
		DD.RFC-822=user(a)sub.dom.top
		DD.RFC-822=user(a)site.bitnet
		DD.RFC-822=user(a)site.uucp

only one*:
	of course this is for nationaly defined mappings
	we use C=us; A= ; P=Internet;   for US controlled top-level domains

smarthost:
	Let me just signal that all 3 french WEps use M.PLUS which
	can be configure to act as a  smarthost/smartgateway:
	M.PLUS routes DD.RFC822 attributes on the basis of the
	RFC domain described by the DD.RFC-822 value, whatever
	the associated SDA might be. This is really a nice feature
	extremely useful for this strategy.

I am wainting for the last version of the ISO/CCITT draft but the
last but one was indeed promoting the form I have given as an
example.
Additionaly, if I remember well there was some reasoning for this choice.
In my mind the only important issue is to decide at last for a
single universal representation and as long as it is "keyworded"
I am not ready to spend energy on discussing the order of
these. SW and interfaces have to be smart enough.
