<para>This parameter provides
the means of indenting the body text relative to
section titles.
For left-to-right text direction, it indents the left side.
For right-to-left text direction, it indents the right side.
It is used in place of the 
<parameter>title.margin.left</parameter> for
all XSL-FO processors except FOP 0.25.
It enables support for side floats to appear
in the indented margin area.
</para>
<para>This start-indent property is added to the fo:flow
for certain page sequences.  Which page-sequences it is 
applied to is determined by the template named
<literal>set.flow.properties</literal>.
By default, that template adds it to the flow
for page-sequences using the <quote>body</quote>
master-reference, as well as appendixes and prefaces.
</para>
<para>If this parameter is used, section titles should have
a start-indent value of 0pt if they are to be
outdented relative to the body text.
</para>

<para>If you are using FOP, then set this parameter to a zero
width value and set the <parameter>title.margin.left</parameter>
parameter to the negative value of the desired indent.
</para>

<para>See also <parameter>body.end.indent</parameter> and
<parameter>title.margin.left</parameter>.
