Great! This has motivated me to re-try the latest DocBook XSL with
PassiveTeX. Conclusion: This appears to work now, with minor fixes:

1. One simple tweak related to the above workaround to get this to
   work with PassiveTeX: Reformulate the calculations of ...minimum
   and ...maximum so they are completely evaluated by the XSLT
   processor (or am I working around an xsltproc limitation here?):

  <xsl:attribute-set name="component.title.properties">
    <xsl:attribute name="keep-with-next.within-column">always</xsl:attribute>
    <xsl:attribute name="space-before.optimum">
      <xsl:value-of select="concat($body.font.master, 'pt')"/>
    </xsl:attribute>
    <xsl:attribute name="space-before.minimum">
      <xsl:value-of select="$body.font.master * 0.8"/>
      <xsl:text>pt</xsl:text>
    </xsl:attribute>
    <xsl:attribute name="space-before.maximum">
      <xsl:value-of select="$body.font.master * 1.2"/>
      <xsl:text>pt</xsl:text>
    </xsl:attribute>
    <xsl:attribute name="hyphenate">false</xsl:attribute>
  </xsl:attribute-set>

   This is only a minor change and completely equivalent to the original,
   so I propose to add this workaround to CVS.

   A similar change can (and probably should, I think) be made to
   <xsl:template name="indexdiv.title">, and probably a few other
   places.


2. PassiveTeX adds spurious vertical space if fo:blocks are
   nested. This has been the case for lists since DocBook XSLT later
   than 1.61.3. I put a workaround into my customization layer that
   "works for me" so far but is probably plain wrong: I removed the
   fo:block from

    <xsl:template match="listitem/*[1][local-name()='para' or ...]">.

   Does anybody have a better idea?


So, good-bye XSLT 1.61.3, PassiveTeX is back on stage!
