toc.indent.width — Amount of indentation for TOC entries
<xsl:param name="toc.indent.width">24</xsl:param> <!-- inconsistant point specification? -->
Specifies, in points, the distance by which each level of the TOC is indented from its parent.
This value is expressed in points, without a unit (in other words, it is a bare number). Using a bare number allows the stylesheet to perform calculations that would otherwise have to be performed by the FO processor because not all processors support expressions.
