Abstract

   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.
