Thanks for sharing your ideas. This is discussion is really
interesting; I've included the fluid-work list on this thread in case
anyone there has some ideas.
> 1 - more about meaning, less about style
I completely agree with this one. I wonder if some of the UI taxonomy
and style guide work that has been going in within the W3C under the
Accessible Rich Internet Application (ARIA) umbrella would be helpful
here? In other words, is it possible to establish some kind of
mapping between the UI primitives identified in the ARIA Roles
document and the CSS classes that should be available to apply
styling to these types of elements?
This specification includes a taxonomy that identifies things like
trees, dialogs, groups, grids, tab containers, tables, etc. I'll ask
Rich Schwerdtfeger tomorrow (he's visiting us here in Toronto right
now) if there has been any work defining style classes for the ARIA

These also make sense to me. Though I'm curious to hear how you think
an "extensibility escape clause mechanism" might look in this context.

Chuck, how do these assumptions mesh with the Portlet 2.0 philosophy?
