how remove dot in orderedlist/listitem?

Hi,

I have fragment of docbook like this:

    <orderedlist inheritnum="ignore" continuation="restarts">

    <listitem><para>FOO</para></listitem>

    <listitem><para>BOO</para></listitem>
    </orderedlist>

I convert this list to xsl-fo, and see (I removed tags):

1. FOO

2. BOO

But I want 

1 FOO

2 BOO

without dots after numbers.

Can not find any preference that can change this behaviour.

Also I try hack fo/list.xsl,

but I can not find where in 
<xsl:template match="d:orderedlist/d:listitem">

dot appear (I am newbie in XSL).

Any suggestions how to remove dots?
