	Title		: Critical Content MIME Parameter

This document describes the use of a mechanism for identifying body 
parts that a sender deems critical in a multi-part Internet mail 
message.  The mechanism described is a parameter to Content-
Disposition, as described by RFC 3204. 
By knowing what parts of a message the sender deems critical, a 
content gateway can intelligently handle multi-part messages when 
providing gateway services to systems of lesser capability.  
Critical content can help a content gateway to decide what parts to 
forward.  It can indicate how hard a gateway should try to deliver a 
body part.  It can help the gateway to pick body parts that are safe 
to silently delete when a system of lesser capability receives a 
message.  In addition, critical content can help the gateway chose 
the notification strategy for the receiving system.  Likewise, if 
the sender expects the destination to do some processing on a body 
part, critical content allows the sender to mark body parts that the 
receiver must process.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
