    As I've stated before, I see no reason not to use a tree control for 
<select multiple>. Nested <optgroup> elements in combination with 
<select multiple> naturally lend themselves to such a control.

    I personally think that we should focus on enhancing <select> and 
<select multiple> to add features including those similar to those 
available in WA1 menus, rather than trying to develop a completely new

    Are any of the differences you described actually in the HTML 4.01 
specification? At first glance, I can't seem to find them. If the 
differences you describe are just the implementation decisions, then I'm 
not sure if they're truly semantic differences to begin with. Either 
way, I would agree that this needs to be discussed in detail.

    With regard to buttons with rounded and square corners, could you 
please explain the differences in how they're used, because from a 
purely graphical standpoint, they seem well into CSS territory.

    I would agree that removed markup should be documented.

    I oppose the idea of having no radio buttons in a radio group 
initially selected. Without some sort of default, there's no way to 
return to the initial state once you've clicked on an option. To allow 
unselected behavior is the functional equivalent of having a default 
option that disappears once you select something other than the default. 
It also creates the following two problems:

1) If you have to worry about options not being selected, you have to 
test to see if nothing was selected. In a strict security sense, the 
server should be checking anyway, but in practice this can trip up a lot 
of webmasters.

2) If the user fails to select an option from the radio group, is this a 
choice the user made, or did they fail to select an option by accident 
(by forgetting to select and option, paging past the radio group, et
