This is already broken for choice checkbox and radio widgets. In these 
cases we have no 1:1 relationship between widget labels and controls. 
(Though sometimes additional 1:1 labels within the widgets do work.)

AFAICS this is a limitation of the HTML specs and no change in zope can 
really fix this. If the 'for' attribute is omitted for checkbox and 
radio widgets (as Fred proposes) there is no relationship at all. If the 
'for' attribute points to a div surrounding the controls (as I propose), 
you can find the ListControl if you are willing to rely on that 
non-standard behavior.
