Note from the field: we implemented Technique 12.3.1 in Bobby, and used that on our beta new web site. We implemented OPTGROUPs in SELECT elements per the requirement. Guess what happened? In Internet Explorer 5 (and maybe earlier, haven't tested) for Mac, drop-down lists had no options show up. It's highly distressing that a browser (and a new one at that) has destructive incompatibility with the HTML standard. But, that being the case, can we have this technique? Nobody can safely implement the requirement. On a related note, about the threshold of triggering if there are 7 or more option elements, there's an article at http://www.humanfactors.com/library/sep00.asp that says the number 7 is from a single 50-year-old study and shouldn't be given too much credence. I wonder if that observation might affect our discussions?
