In this document, the "message context" conveys information about the way the user expects to interact with the message. For example, a message may be e-mail, voice mail, fax mail, etc. A smart UA may have specialized behavior based on the context of the message. This document specifies a RFC 2822 header called "Message-Context". Burger, et al.

Content-Disposition gives clues to the receiving User Agent (UA) for how to display a given body part. Message-Context can give clues to the receiving UA forShow full document text
