msxml4 data islands and "xsl:copy-of"

Because of the need for some javascript code, I need a data island.  In
my style sheet, if an xml document(seminar_info) is passed in as a
parameter, I can do this with that parameter to get that document as a
data island:

    <xml id="dsoSeminar"><xsl:copy-of
select="msxsl:node-set($seminar_info)" /></xml>
   </body>
   </html>

   </xsl:template>
   </xsl:stylesheet>

but my question is, if I want to make a data island out of the main
document that is being rendered by the style sheet, how do I do that? 
I've tried these:

   <xml id="dsoSeminar"><xsl:copy-of select="document()" /></xml>
   <xml id="dsoSeminar"><xsl:copy-of select="document('')" /></xml>
   <xml id="dsoSeminar"><xsl:copy-of select="." /></xml>

and none of them work.

TIA.
