<p>
The class template <code>priority_queue</code> declares signatures for a move
constructor and move assignment operator in its class definition.
However, it does not provide a definition (unlike <code>std::queue</code>, and
proposed resolution for <code>std::stack</code>.) Nor does it provide a text clause
specifying their behaviour.
