     <p>Additionally, the sending entity adds an element <tt>&lt;sticker/&gt;</tt> to the message. This element carries an attribute <tt>pack</tt> referring to the id of the pubsub item carrying the sticker pack. If the sticker pack resides on a pubsub item other than the senders personal eventing (PEP) node named "urn:xmpp:stickers:0", the sending entity must add additional attributes <tt>jid</tt> and <tt>node</tt>, referring to the jid of the pubsub node and the name of the node, respectively.</p>
     <p>The sending entity SHOULD use the <tt>&lt;file/&gt;</tt>'s <tt>&lt;desc/&gt;</tt> content as the message body, except if the sticker was selected based on a suggestion, in which case the content of the corresponding <tt>&lt;suggest/&gt;</tt> SHOULD be used.</p>
