A MIX client MAY request that the server return this additional information that annotates roster elements with MIX capability. The server MUST return the additional information. The request is made by extending the standard roster get request by adding a child element <annotate/> to the <query/> element. The <mix-info-request/> is qualified by the ‘urn:xmpp:mix:roster:0' namespace.</p>
