  16 <p id="label-iterators-concepts">All iterators in MPL are classified into three iterator concepts, or
  17 <cite>categories</cite>, named according to the type of traversal provided. The
  18 categories are: <a class="reference internal" href="./forward-iterator.html">Forward Iterator</a>, <a class="reference internal" href="./bidirectional-iterator.html">Bidirectional Iterator</a>, and
  19 <a class="reference internal" href="./random-access-iterator.html">Random Access Iterator</a>. The concepts are hierarchical:
  20 <a class="reference internal" href="./random-access-iterator.html">Random Access Iterator</a> is a refinement of <a class="reference internal" href="./bidirectional-iterator.html">Bidirectional Iterator</a>,
  21 which, in its turn, is a refinement of <a class="reference internal" href="./forward-iterator.html">Forward Iterator</a>.</p>
  22 <p>Because of the inherently immutable nature of the value access, MPL
  23 iterators escape the problems of the traversal-only categorization
