    Thanks! The adding of "pt" works (makes more sense, indeed, to add a
    value..),
     except for the "proportional-column-width", where the same code does not
    work any more.

    XML:
    <colspec colname="col1" colwidth="72*"/>
    <colspec colname="col2" colwidth="134*"/>

    XSL:
      <xsl:if test="contains($colwidth, '*')">
        <xsl:text>proportional-column-width(</xsl:text>
        <xsl:value-of select="substring-before($colwidth, '*')"/>
        <xsl:text>)</xsl:text>
      </xsl:if>

    Resultant FO:
    <fo:table table-omit-header-at-break="false"
    table-omit-footer-at-break="false" empty-cells="show"
    keep-with-previous="always" keep-together.within-page="always"
    padding-top="3pt" border-bottom-width="0.4pt" border-bottom-style="solid"
    padding-bottom="3pt" text-align="center" space-after="24pt" width="NaNpt"
    start-indent="(323pt - NaNpt)div 2" table-layout="fixed">
    <fo:table-column column-number="1"
    column-width="proportional-column-width(72)"/>
    <fo:table-column column-number="2"
    column-width="proportional-column-width(134)"/>

    I guess I need to create another variable to specify the sum of proportional
    column widths?
