Why is that a problem?

Say your code has

      <OPTGROUP label="books">
              <OPTGROUP label="fiction">
                     <OPTION>Treasure Island</OPTION>
              <OPTGROUP label="nonfiction">
                     <OPTION>Art of War</OPTION>



The compliant browser would render

      [fiction >]
           [Treasure Island]
      [nonfiction >] 
           [Art of War]

while an older browser would show

Treasure Island
Art of War

I don't see a problem with that - it looks like perfectly graceful
degradation to me...
