<xsl:template match="Subject">
  <p>
    <xsl:value-of select="concat(substring(., 1, 20), substring('...', 1 div (string-length(.) > 20), 3))" />
  </p>
</xsl:template>

It uses the Becker method for adding the '...' the string length is greater than 20. See the archives or e.g. Jeni's book for further explanation.
