After reviewing national body comments to n3690, this library component was voted out from C++14 working paper into a separate Technical Specification. This container is not a part of the draft C++14 as of n3797

std::experimental::dynarray is a sequence container that encapsulates arrays with a size that is fixed at construction and does not change throughout the lifetime of the object.
The elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets on regular pointers to elements. This means that a pointer to an element of a dynarray may be passed to any function that expects a pointer to an element of an array.
There is a special case for a zero-length array (the number of elements was specified as zero during construction). In that case, array.begin() == array.end(), which is some unique value. The effect of calling front() or back() on a zero-sized dynarray is undefined.
