The ``iterator_category`` member of ``iterator_facade`` is
``facade_iterator_category(CategoryOrTraversal, value_type,
reference)``, as specified by the following pseudo-code:
.. include:: facade_iterator_category.rst
If ``CategoryOrTraversal`` is ``use_default`` then
``iterator_traversal<Derived>::type`` is convertible to the most
derived standard traversal tag type to which
``iterator_traversal<Iterator>::type`` is also convertible, and not to
any more-derived traversal tag type. Otherwise
``iterator_traversal<Derived>::type`` is convertible to the most
derived standard traversal tag type to which ``CategoryOrTraversal``
is also convertible, and not to any more-derived traversal tag type.
The ``enable_if_interoperable`` template used above is for exposition
purposes. The member operators should be only be in an overload set
provided the derived types ``Dr1`` and ``Dr2`` are interoperable,
