+<A NAME="sec4"><H3>Description</H3></A>
+<P><SAMP>use_facet()</SAMP> returns a reference to the corresponding facet contained in the <SAMP>locale</SAMP> argument. You specify the facet type by explicitly including the template parameter (see the example below). If that facet is not present, then <SAMP>use_facet()</SAMP> throws <B><I><A HREF="bad-cast.html">bad_cast</A></I></B>. Otherwise, the reference remains valid for as long as any copy of the locale exists.</P>
