This combination looks pretty good to me:

  <xsl:template name="format.footnote.mark">
    <xsl:param name="mark" select="'?'"/>
    <fo:inline baseline-shift="super" font-size="70%">
      <xsl:copy-of select="$mark"/>
    </fo:inline>
  </xsl:template>

[Above is what I suggested in a previous mail, but with a more
reasonable 70% scale factor.]

  <xsl:attribute-set name="normal.para.spacing">
    <xsl:attribute name="space-before.optimum">1em</xsl:attribute>
    <xsl:attribute name="space-before.minimum">0.8em</xsl:attribute>
    <xsl:attribute name="space-before.maximum">1.2em</xsl:attribute>
    <xsl:attribute name="line-height-shift-adjustment">
      disregard-shifts
    </xsl:attribute>
  </xsl:attribute-set>

With 10 point Times Roman, the superscript footnote marks seem to miss
the descenders from the line above and are not too small, and the line
spacing is unaffected.  However, if you didn't like 90%, Tobias,
you're not going to like 70%.  :-) You may have to keep trying, but
this looks nice to me.  Also, this could break all manner of other
formatting with Norm's FO stylesheets for all I know, in particular
inline graphics -- I've only tested it on a minimal input to see what
it did for footnotes.  There is bound to be a better way.
