      accessing the Internet for Catalog files. The resolver is configured
      through the <code class="literal">CatalogManager.properties</code> and
      <code class="literal">xml-catalog.xml</code> files in the
      <code class="literal">src/resolver</code> directory of the distribution.</p><p>If you update e.g. the Docbook XML version, you must also update
      the catalog file to match the new version. Else the rendering process
      will have no knowledge of your changes and access the Internet to
      download the required DTD files.</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch04s02.html">Prev</a>&nbsp;</td><td width="20%" align="center"><a accesskey="u" href="ch04.html">Up</a></td><td width="40%" align="right">&nbsp;<a accesskey="n" href="ch04s04.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">4.2&nbsp;DocBook reference files&nbsp;</td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top">&nbsp;4.4&nbsp;Docbook Source files</td></tr></table></div></body></html>
