Alignment of external graphic inserted as style icon

[Jean-Francois Weissmann <jfwfr@yahoo.fr>]

Hi,
I defined a style for my weblink as follows:

<xsl:template match="d:link[@xrefstyle = 'web']">
  <xsl:param name="content">
    <xsl:call-template name="simple.xlink">
      <xsl:with-param name="content">
        <xsl:apply-templates/>
      </xsl:with-param>
    </xsl:call-template>
  </xsl:param>
  <fo:external-graphic src="url({$weblink})" height="9pt" content-width="scale-down-to-fit »/>
  <xsl:text>&#160;</xsl:text>
  <fo:inline color="#0066cc" text-decoration="underline">
    <xsl:call-template name="anchor"/>
    <xsl:if test="@dir">
      <xsl:attribute name="direction">
        <xsl:choose>
          <xsl:when test="@dir = 'ltr' or @dir = 'lro'">ltr</xsl:when>
          <xsl:otherwise>rtl</xsl:otherwise>
        </xsl:choose>
      </xsl:attribute>
    </xsl:if>
    <xsl:copy-of select="$content"/>
  </fo:inline>
</xsl:template>

The problem is that even if my SVG file behind the variable $weblink is 10pt x 10pt, and the size of my body text is also 10pt, I can not manage to correctly align the icon and the text: the icon is always sort of "aligned in the upper left corner" of the container where the actual SVG icon is display. Does a proper tie like vertical-align would work in that case, any other ideas?

Many Thanks,
