  <p>For each of the concepts documented here, the library includes an
  identical concept checking class whose name ends in
  “<code>Concept</code>” For example, in
  addition to <code>RandomAccessIterator</code>, the library defines a
  <code>RandomAccessIteratorConcept</code> class template.</p>
