http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Interface.Messages.html#org.freedesktop.Telepathy.Channel.Interface.Messages.Message_Part «content-type (s) The MIME type of this part. See the documentation for ReceivedMessage for notes on the special status of "text/plain" parts.» ReceivedMessage don't exist, perhaps that should be MessageSent?
I called it MessageReceived in the end; the cross-reference is indeed wrong. The documentation of MessageSent talks about the CM synthesizing text/plain versions when *sending* formatted text, but we should also explicitly say (in MessageReceived?) that if a CM *receives* formatted text, it must synthesize a text/plain alternative. Patches welcome.
