  In general this won't work because the namespace node needs to be "in-scope"
i.e. held by a parent of the node referencing it, and usually if you're missing
a namespace it's because the parent was from the old tree.

   <a>
      <b xmlns:foo="foo">
         <c foo:attr="">
            <d xmlns:bar="foo">
               <foo:e/>
            </d>
         </c>
      </b>
   </a>

  though possible is unlikely. If you detach <c> the namespace used by e
could be remapped to the one held by d, but it won't fix the problem for 
foo:attr on c anyway...
  So no I think it makes little sense to do what you suggest.
