-<para>The stylesheets are capable of generating both default
-and custom CSS stylesheet files.  The parameters 
-<parameter>make.clean.html</parameter>,
-<parameter>docbook.css.source</parameter>, and
-<parameter>custom.css.source</parameter> control that feature.</para>

-<para>If you require that CSS styles reside in the HTML 
-<tag>HEAD</tag> element instead of external CSS files,
-then set the <parameter>generate.css.header</parameter>
-parameter to nonzero (it is zero by default).
-Then instead of generating the CSS in external files,
-they are wrapped in <tag>style</tag> elements in
-the <tag>HEAD</tag> element of each HTML output file.
