+  <p>Some instant messaging implementations of the Jabber/XMPP protocols have long supported the ability for IM users to be online but appear invisible. The existing protocols for doing so are:</p>
   <ul>
     <li><p>&xep0018; -- this protocol is not compatible with &xmppcore; and &xmppim;, and the speciifcation does not provide reliable documentation of the protocol in use since many server implementations support presence of type "invisible" but not presence of type "visible".</p></li>
     <li><p>&xep0126; -- this protocol is in many ways a mis-use of privacy lists for the temporary purpose of appearing invisible rather than the intended purpose of permanently blocking communications.</p></li>
