<para>The <parameter>marker.section.level</parameter> parameter
controls the depth of section levels that may be displayed
in running headers and footers.  For example, if the value
is 2 (the default), then titles from <tag>sect1</tag> and 
<tag>sect2</tag> or equivalent <tag>section</tag>
elements are candidates for use in running headers and
footers.
</para>
<para>Each candidate title is marked in the FO output with a
<tag>&lt;fo:marker marker-class-name="section.head.marker"&gt;</tag>
element.
</para>
<para>In order for such titles to appear in headers
or footers, the <literal>header.content</literal>
or <literal>footer.content</literal> template
must be customized to retrieve the marker using
an output element such as:
</para>
<programlisting>
&lt;fo:retrieve-marker retrieve-class-name="section.head.marker"
                       retrieve-position="first-including-carryover"
                       retrieve-boundary="page-sequence"/&gt;
</programlisting>
