rdf/a calendar demo

FYI:

0068.html>

The example RDF/A event markup looks like so:

<p about="#xtech_talk" role="cal:Vevent"
     xmlns:cal="http://www.w3.org/2002/12/cal/ical#";
     xmlns:dc="http://purl.org/dc/elements/1.1/";>
         <span property="cal:location">At the XTech Conference</span>,
         I'm giving
         <span property="cal:summary">a talk about web widgets</span>,
         on
         <span property="cal:dtstart" content="20060508T180000Z">
             May 8th at 10am
         </span>
         <span property="cal:duration" content="PT1H">for 1 hour</span>,
         <span property="cal:dtend" content="20060508T190000Z" />
         <span property="dc:creator">DanC</span>
</p>

This sort of relates to my comments about captions on the TC list.  
E.g., here they say that a an element with a property attribute  
represents a property of the containing element with about attribute.
