An Occupant-id tag.
An <occupant-id/> tag is set by the MUC.
This is useful in semi-anon MUCs (and MUC-PMs) as a stable identifier to
prevent the usual races with nicknames.
Without occupant-id, getting the following messages from MUC history would
prevent a client from asserting senders are the same entity:
<message type='groupchat' from='foo@muc/nick1' id='message1'>
<body>Some message</body>
<occupant-id xmlns='urn:xmpp:occupant-id:0' id='unique-opaque-id1'/>

<body>Some correction</body>

<replace xmlns='urn:xmpp:message-correct:0' id='message1'/>
