<para>This parameter provides
|
|
the means of adjusting the left margin for titles
|
|
when the XSL-FO processor being used is
|
|
an old version of FOP (0.25 and earlier).
|
|
It is only useful when the <parameter>fop.extensions</parameter>
|
|
is nonzero.</para>
|
|
|
|
<para>The left margin of the body region
|
|
is calculated to include this space,
|
|
and titles are outdented to the left outside
|
|
the body region by this amount,
|
|
effectively leaving titles at the intended left margin
|
|
and the body text indented.
|
|
Currently this method is only used for old FOP because
|
|
it cannot properly use the <parameter>body.start.indent</parameter>
|
|
parameter.
|
|
</para>
|
|
<para>
|
|
The default value when the <parameter>fop.extensions</parameter>
|
|
parameter is nonzero is -4pc, which means the
|
|
body text is indented 4 picas relative to
|
|
the titles.
|
|
The default value when the <parameter>fop.extensions</parameter>
|
|
parameter equals zero is 0pt, and
|
|
the body indent should instead be specified
|
|
using the <parameter>body.start.indent</parameter>
|
|
parameter.
|
|
</para>
|
|
<para>
|
|
If you set the value to zero, be sure to still include
|
|
a unit indicator such as <literal>0pt</literal>, or
|
|
the FO processor will report errors.
