xing_suite</tt> is not meant to be used as is. A couple of

      policy functions must be supplied by subclasses of

      <tt>indexing_suite</tt>. However, a set of <tt>indexing_suite</tt>

      subclasses for the standard indexable STL containers will be provided,

      In most cases, we can simply use the available predefined suites. In

      some cases, we can refine the predefined suites to suit our needs.
