Um, I'd suggest that this by itself isn't really all that helpful. It
might help to add some more explanatary text together with
recommendations on what to do. E.g.,

 - should an implementation just configure the address and use it
   anyway? (I doubt this, as this implies we should just punt on DAD)

 - Assume there is a DOS attack, wait a while, and try again? (hoping
   the bad guy goes away in the meantime)

 - generate a new IID and try again? And if so, are there
   recommendations on what kind of ID? And if there is a  DOS attack
   in progress, why would  trying *any* address result in success?

 - Try generating a new address, but use exponential backoff in
   delaying after each failed attempt?

 - something else? (or some combination of the above?)
