Try using <xsl:template match="//rfc[1]"> <!-- Add link to RFC here --> </xsl:template>
I'm not totally sure this will work, but I think since the match is on the /descendant-or-self axis of the root node, this will only match on the first rfc element in the document.

I have a custom element <rfc> to put references to RFC. I want to add a small blurb explaining how to get a RFC but, since there are many references to RFC in a given text, I want it to appear only the first time. I have no idea on how to do that. Both XSL and DSSSL are stateless so I cannot keep a "already_seen" variable. To make things more concrete, here is the way I do it in LaTeX: % The first time we mention a RFC, add a reference \newcounter{rfcfirst} \newcommand{\rfc}[1]{RFC #1\ifthenelse{\boolean{rfcfootnote}}% {\ifthenelse{\value{rfcfirst} = 0}% {\footnote{Pour voir le RFC de num�ro NNN, \url{http://www.ietf.org/rfc/rfcNNN.txt}, par exemple \url{http://www.ietf.org/rfc/rfc#1.txt}}\stepcounter{rfcfirst}}% {}% }% {}% }
