Interesting, since the implementation of resize() calls something like 
"container_detail::insert_default_constructed_n_proxy" I assumed the 
documentation was OK.

Yes, this should be enough, provided that the "Effects" sentences are 
also corrected, i.e. "New elements are default constructed" will be 
changed to something like "New elements are value/default -initialized" 
(both for the constructor and resize() method).

Will do.
