CHECKLIST and "implementation defined"

[Phil Edwards <phil at jaj dot com>]

17_intro/CHECKLIST is horribly out of date.  No particular blame there,
it just is.  So I'm starting to bring it up to date, at least partially.

The containers have status flags for each of their required members.  The
container as a whole then gets the "worst" scoring flag of all its members.
Right now we have a lot of containers that look like this:

 X  class foo {
    public:
 T    typedef typename Allocator::reference         reference;
 T    typedef typename Allocator::const_reference   const_reference;
 X    typedef implementation defined                iterator;
 X    typedef implementation defined                const_iterator;
 T    typedef implementation defined                size_type;
 T    typedef implementation defined                difference_type;

 T    everything else
    };

I don't consider the iterators to be "partially implemented or buggy,"
so this is a proposal to upgrade their status to T.  Thoughts?
