I have several questions with regard to the working paper N3225 (C++0x working draft):

1. Where the working draft specifies preconditions for shrink_to_fit member function of std::vector and std::deque?

2. Where the working draft specifies preconditions for 'void reserve(size_type n)' member function of std::vector?

3. Does a call to 'void resize(size_type sz)' of std::vector require the element type to be DefaultConstructible? If yes, why such requirement is not listed in the Requires paragraph?

4. Does a call to 'void resize(size_type sz)' of std::vector require the element type to be MoveAssignable because the call erase(begin() + sz, end()) mentioned in the Effects paragraph would require the element type to be MoveAssignable?

5. Why CopyInsertable requirement is used for 'void resize(size_type sz)' of std::vector instead of MoveInsertable requirement?
