   The libxml extension is enabled by default, although it may be disabled with
   <option role="configure">--disable-libxml</option>. 
  </para>
  <para>
   The optional <option role="configure">--with-libxml-dir</option>
   directive is used to specify the location of <literal>libxml</literal>
   on the system that PHP is being compiled on, otherwise only the
   default locations are scanned. The <literal>configure</literal> process
   checks for libxml (specifically, <literal>xml2-config</literal>) in the
   following order:
  </para>
  <orderedlist>
   <listitem>
    <para>
     The location ([DIR]) specified with <option role="configure">--with-libxml-dir</option> 
     ([DIR]=<filename>/bin/xml2-config</filename>)
    </para>
   </listitem>
   <listitem>
    <para>
     <filename>/usr/local/bin/xml2-config</filename>
    </para>
   </listitem>
   <listitem>
    <para>
     <filename>/usr/bin/xml2-config</filename>
    </para>
   </listitem>
  </orderedlist>
  <para>
   If <literal>configure</literal> cannot find <filename>xml2-config</filename> in the directory
   specified by <option role="configure">--with-libxml-dir</option>, then
   it'll continue on and check the default locations.
