You can tell the pioneers by the arrows in their chests, and I
appreciate your willingness to make the effort to explore the
consequences of the proposal and give feedback.  That has made it
clear that at the very least I could/should have done better
explaining what the design patterns were that followed from the core
of the proposal.  I am a bit disappointed that you haven't responded
to my effort to do this:

I can now make that other example public (my thanks to Jon Gunderson
of the Illinois Center for Information Technology Accessibility
(iCITA)):

 http://www.w3.org/XML/2008/04/ARIA-Testing/uct-colon-html.html
 http://www.w3.org/XML/2008/04/ARIA-Testing/uct-colon-xhtml.html

These tests were converted from the 'aria-' iCITA examples using the
above methodology, very easily, and work in IE 7 as well as Firefox,
Opera and Safari (and, with an edited and rebuilt accessibility
module in Firefox 3b5, with the ORCA screen-reader).
