Perhaps instead of new classes and protocols, we could just do this  
completely in javascript.  Here is a general example, probably all  
the function names would end up being different:

<div id="hcard-Alex-Faaborg" class="vcard">
  <span class="fn">Alex Faaborg</span>
  <div class="org">Mozilla</div>
  <div class="adr">
   <div class="street-address">1981 Landings Dr. Building S</div>
   <span class="locality">Mountain View</span>
   <span class="region">CA</span>
   <span class="postal-code">94043</span>
   <script type="text/javascript">
  	if (navigator.microformatAware("hCard")){
   	document.write("<a href='#' onclick='navigator.sendToAddressBook 
('hcard-Alex-Faaborg')'>Add to Address Book</a>");
   	document.write(", ")
   	document.write("<a href='#' onclick='navigator.sendToMap('hcard- 
Alex-Faaborg')'>Send to Map</a>");

We can include these actions on context menus, and in the browser UI  
(similar to Operator's interface).  However, I'm not sure content  
creators would be too happy with Firefox modifying their pages by  
literally injecting UI.
