I think you're right that a full-blown Human Interface Guide is beyond 
where we're at right now. But I don't think it's too much to define what 
our UI elements actually are though, for the purpose of defining browser 
support levels. I think that list (of elements) is actually pretty short 
(< 10), and includes:

   Epoz
   folder_contents table
   action menus
   date widget
   "Navigational Plone Tabs(tm)" :p

Absolutely! Once the levels are nailed down ...

This is behind my Mac IE question. I would like to support Mac IE at 
Level 3 but not Level 2.

Do we want a level 1.5 (partial CSS support)? My initial response is 
"no," but I'd be interested to hear what others think.
