Compact spacing in <blockquote> ?!

["Euis Luhuanam" <eluhu6@gmail.com>]

Hi,

Based on http://lists.oasis-open.org/archives/docbook-apps/200607/msg00032.html
I managed to compact the spaces on the top and bottom of the list.
= = = = =
  <xsl:attribute-set name="list.block.spacing">
   <xsl:attribute name="space-before.optimum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>1em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-before.maximum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>1.2em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-before.minimum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>0.8em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-after.optimum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>1em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-after.maximum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>1.2em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-after.minimum">
    <xsl:choose>
     <xsl:when test="@spacing = 'compact'">0em</xsl:when>
     <xsl:otherwise>0.8em</xsl:otherwise>
    </xsl:choose>
   </xsl:attribute>
  </xsl:attribute-set>
= = = = =

I would like to know, if we can also compact the top and
bottom of a blockquote?

thank you and regards,
