XEP-0107: User Mood
A user MAY provide a mood extension in a specific message in order to lend a defined emotional tone to the text.
Example 5. User Provides Mood in Message
\<message from='romeo@montague.lit/pda'
to='juliet@capulet.lit'
type='chat'>
\<body>A thousand times good night!\</body>
\<mood xmlns='http://jabber.org/protocol/mood'>
\<sad/>
\<text>curse my nurse!\</text>
\</mood>
\</message>
This stanza works if the server doesn't support PEP and send my mood in message.It would be nice to have this option in gajim!
