---- yes, these are part of hCalendar, but they are very obscure and
not very well implemented in the wild. At the moment the cheat sheet
is NOT the end-all-be-all for possible properties.

If you have a solid reason that you would NEED any of these items
please send us your URL. I am opened to discussing some of these
properties, but not in a hypotetical senario - if we are going to
spend the time looking into these - it needs to be in context of real
