<para>The region inner extent is the width of the optional
text area next to the inner side (binding side) of the
body region.  </para>

<para>For double-sided output, this side region 
is <literal>fo:region-start</literal> on a odd-numbered page,
and <literal>fo:region-end</literal> on an even-numbered page.</para>

<para>For single-sided output, this side region
is <literal>fo:region-start</literal> for all pages.</para>

<para>This correspondence applies to all languages,
both left-to-right and right-to-left writing modes.</para>

<para>The default value of this parameter is zero.  If you enlarge this extent,
be sure to also enlarge the <parameter>body.margin.inner</parameter>
parameter to make room for its content, otherwise any text in
the side region may overlap with the body text.</para>
