You guys should also look at micro-formats. This would allow HTML something like the following:
<table class="vcard"> <tr><td class="fn">Jonathan</td><td class="n">Dickinson</td></tr> <tr><td>Jabber ID:</td><td><a class="url jid" href="xmpp://[EMAIL PROTECTED]">[EMAIL PROTECTED]</a></td></tr> </table> In addition to the <link> stuff. All you would need to do is to extend the format with a jid field. Jonathan
