How to adjust listitem indentation for variablelists?

Hello all,

I'm looking for a way to adjust the amount of indentation of the
listitems of a varlistentry. The variablelist is being rendered as a
list (i.e. the term preceding the listitem in the print output), using
the FO parameter:

    <xsl:param name="variablelist.as.blocks">1</xsl:param>


Is what I want possible? If so, I'd very much appreciate a direction.


Thanks in advance,

Erik Leunissen.
