   Something else that needs a way to be represented (although there's no 
   markup in HTML to make use of it): recurring events. Perhaps the 
   ISO dattime standard can be given an extension, so that it represents a 
   start time, end time, and possibly a recurrance length (ie, every hour, 
   every day, once a week, monthly, every four weeks, etc.)

Actually this has been possible in HTML for a long time...just not in
some of the versions promulgated by the W3C. HTML3 and its heirs and
assigns allows:

   <head>
     <title>List of events</title>
     <meta name="DC.whatever-it-is-for-weekly-reoccurrence" content="foo">
     <range id="foo" from="abc" until="def">
     <!-- more <meta><range> pairs -->
   </head>
     <body>
       <h1>List of events</h1>
       <dl>
         <dt id="abc">Weekly beerbust</dt>
         <dd id="def">This is held at Moe's Tavern each Friday at
           5.30pm and is paid for by the boss</dd>
         <!-- more of them -->
       </dl>
     </body>
   </html>

This is a small abuse of the CONTENT attribute: it would be easier if
META had an IDREF attribute. 

But you're right in saying HTML has no DATE markup. It was proposed
once for HTML+ but at the time no-one on the browser side felt a need
to implement it :-)
