How about using attribute sets?


<?xml version="1.0"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nl "&#xd;&#xa;">
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                xmlns:fo="http://www.w3.org/1999/XSL/Format";
                version="1.0">

<xsl:param name='hd-size' select="10"/>

<xsl:attribute-set name="font-metrics">
  <xsl:attribute name="font-size">
    <xsl:value-of select="$hd-size"/>pt</xsl:attribute>
  <xsl:attribute name="space-before.minimum">
    <xsl:value-of select="round(0.8 * $hd-size)"/>pt</xsl:attribute>
  <xsl:attribute name="space-before.maximum">
    <xsl:value-of select="round(1.2 * $hd-size)"/>pt</xsl:attribute>
  <xsl:attribute name="space-before.optimum">
    <xsl:value-of select="$hd-size"/>pt</xsl:attribute>
</xsl:attribute-set>

<xsl:template match="item">
  <fo:block xsl:use-attribute-sets="font-metrics">
    <xsl:apply-templates/>
  </fo:block>
</xsl:template>

</xsl:stylesheet>

Objective is to provide everything in relative sizes,
such that I can provide a variant (font size) for any users
preference.

I think the above will do that for you.


I hope this helps.
