In the 1980's (I think) there was an EEC initaiative called Trade Electronic 
Data Interchange Systems (TEDIS - now I believe defunct) which defined rules 
to allow successful interworking of EDI data using a basic 1984 X.400 service 
which were referred to as TEDIS-conformant P2.

I understand that amongst the recommendations were:

1.   One EDI interchange per mail message.
2.   One "To" recipient (no cc or bcc recipients).
3.   No subject field to be used.
4.   A single IA5 body-part.

My question is:  Are these recommendations still relevant in the second half 
of the 1990's, particularly in the light of the '88 and '92/'93 X.400 
recommendations and functionalities, and are they relevant outside of the EEC 
- specifically in Asia?

I would greatly appreciate advice from anyone who is familiar with this issue, 
either by a post to this newsgroup or by direct E-Mail to myself.
Many thanks.
