In instant messaging (IM) systems@ it is useful to know during an IM conversation whether the other party is composing a message; e.g.@ typing or recording an audio message. This document defines a new status message content type and XML namespace that conveys information about a message being composed. The status message can indicate the composition of a message of any type@ including text@ voice@ or video. The status messages are delivered to the instant messaging recipient in the same manner as the instant messages themselves.
