</h4>
<p>
The user of <a href="sequence_facade.html" title="Sequence Facade"><tt class="computeroutput"><span class="identifier">sequence_facade</span></tt></a> derives his sequence
type from a specialization of <a href="sequence_facade.html" title="Sequence Facade"><tt class="computeroutput"><span class="identifier">sequence_facade</span></tt></a> and passes the derived
sequence type as the first template parameter. The second template parameter
should be the traversal category of the sequence being implemented. The 3rd
parameter should be set to <tt class="computeroutput"><span class="identifier">mpl</span><span class="special">::</span><span class="identifier">true_</span></tt>
if the sequence is a view.
</p>
<p>
The user must the implement the key expressions required by their sequence
type.
