Thanks a lot, that did it. I had to modify it slightly to fit into the
section/title template in titlepage.mode. There I've inserted the

   <!-- get our own label markup without gentext -->
   <xsl:variable name="label">
    <xsl:apply-templates select="$section" mode="label.markup">
     <xsl:with-param name="allow-anchors" select="1"/>
    <xsl:text>. </xsl:text>

   <xsl:variable name="label.length">
    <xsl:value-of select="concat(string-length($label), 'em*0.37')"/>

   <!-- change title from flat string to list/table, section.heading
        will xsl:copy-of it into place -->
   <xsl:variable name="title">
    <fo:list-block provisional-label-separation="0.2em"
      <fo:list-item-label end-indent="label-end()" text-align="start">
        <xsl:copy-of select="$label"/>
      <fo:list-item-body start-indent="body-start()">
       <fo:block hyphenation-remain-character-count="5"
        <xsl:apply-templates select="$section" mode="title.markup">
         <xsl:with-param name="allow-anchors" select="1"/>

It works fine and the estimate of length(label)*0.37 is surprisingly
close to what it looked like with just a space.

Thanks again.
bye, Micha
