But both XSL and DSSSL has query language, something which is not
available in LaTeX. Try something like:

<xsl:template match="rfc">
  ... process element ...
  <xsl:if test="not(preceding::rfc)">
    ... stuff to appear when we are on a first occurence of rfc
element...
  </xsl:if>
</xsl:template>
