<para>If optional side regions on a page
are established using parameters such as
<parameter>body.margin.inner</parameter>, 
<parameter>region.inner.extent</parameter>, etc., then this
parameter determines what happens at the corners where the
side regions meet the header and footer regions.</para>

<para>If the value of this parameter is <literal>true</literal>,
then the side regions have precedence and extend higher
and lower, while the header and footer regions are narrower
and fit inside the side regions.</para>

<para>If the value of this parameter is <literal>false</literal>
(the default value), then the header and footer regions 
have precedence and extend over and below the side regions.
Any value other than <literal>true</literal> or
<literal>false</literal> is taken to be <literal>false</literal>.</para>

<para>If you need to set precedence separately for
individual regions, then you can set four
parameters that are normally internal to the stylesheet.
These four parameters are normally set based
on the value from <parameter>side.region.precedence</parameter>:</para>

<programlisting>region.before.precedence
region.after.precedence
region.start.precedence
region.end.precedence</programlisting>

<parameter>region.inner.extent</parameter>,
<parameter>region.outer.extent</parameter>,
<parameter>body.margin.inner</parameter>,
<parameter>body.margin.outer</parameter>.
