Excellent detail work, Dave.
I think that example (and discussion about
new/old browsers) is a great one to
copy-and-paste into the spec.

This is invalid with respect to the Oct 24th Draft of HTML 4.0.
You need to add the end tags for OPTGROUP, and to drop the value
attribute on OPTGROUP. It would also make sense to tailor the
labels for the options and groups for viewing on both old and
new browsers, e.g.
<SELECT name="ComOS">
<OPTGROUP label="Washington">
<OPTION VALUE="Vancouver WA"
label="Vancouver">Vancouver, Washington
</OPTGROUP>
<OPTGROUP label="British Columbia">
<option value="Vancouver BC"
label="Vancouver">Vancouver, British Columbia
</OPTGROUP>
</SELECT>
People using old browsers would see the flat list:
Vancouver, Washington
Vancouver, British Columbia
People using new browsers would see the hierarchy:
Washtington
Vancouver
British Columbia
Vancouver
I hope you will agree that this provides a workable solution
that allows the same markup to be viewed effectively on both
old and new browsers.
