Subject: text/plain; charset=iso-8859-1 and its downgrading

Sorry if my question has already been discussed on this list...
I would like to know what is the correct behaviour for an X400-SMTP 
gateway, when it receives a 'text/plain; charset=iso-8859-1' and has to 
downgrade it to an X400-84 bodypart :
. rfc1494 tells to create an EBP General-Text and rfc1496 tells that such 
an EBP should be encapsulated in an IA5 bodypart, as it has been 
received, because General-Text EBP has no corresponding 84 Basic Form,
. but X419 tells that General-Text EBP downgrading should be done by 
creating an Undefined bodypart.
What is the right behaviour ?
