Subject: Re: [docbook-apps] Changing line spacing in variablelists

Hi Bob,
The extra space is coming from the <para> element embedded in the listitem.
The para element generates a block with its own spacing coming from the
"para.properties" attribute-set.  I was able to remove the extra space by
customizing para.properties as follows to make it
conditional:

     <xsl:attribute-set name="para.properties">
         <xsl:attribute name="space-before.maximum">
             <xsl:choose>
                 <xsl:when test="ancestor::varlistentry">0pt</xsl:when>
                 <xsl:otherwise>1.2em</xsl:otherwise>
             </xsl:choose>
         </xsl:attribute>
         <xsl:attribute name="space-before.optimum">
             <xsl:choose>
                 <xsl:when test="ancestor::varlistentry">0pt</xsl:when>
                 <xsl:otherwise>1.0em</xsl:otherwise>
             </xsl:choose>
         </xsl:attribute>
         <xsl:attribute name="space-before.minimum">
             <xsl:choose>
                 <xsl:when test="ancestor::varlistentry">0pt</xsl:when>
                 <xsl:otherwise>.8em</xsl:otherwise>
             </xsl:choose>
         </xsl:attribute>

     </xsl:attribute-set>

Note that this applies to all paras in varlistentry, so if you have two
paras in a listitem, there will be no space between them as well.
