Well it's kinda ugly, but you could do:

<xsl:if test="$debug">
  <!-- start comment -->
  <xsl:text disable-output-escaping="yes">&lt;--</xsl:text>
  <!-- copy the document -->
  <xsl:copy-of select="/" />
  <!-- end comment -->
  <xsl:text disable-output-escaping="yes">--></xsl:text>
</xsl:if>

I would normally stay well away from disable-output-escaping but Mike
Kay used it the other day in a similar situation so I don't feel so
bad.

I hope that helps,

Jeni
