PI as a variable value

Hi all,

Is it possible, in a two-pass processing, to define a variable of the first pass with a value that is a PI :

  <xsl:variable name="nbthinsp">
	<xsl:processing-instruction name="nbthinsp">
	  
	</xsl:processing-instruction>
  </xsl:variable>

such that $nbthinsp give the value <?nbthinsp?> in the output of the first pass. With the code above, $nbthinsp is empty.

Many thanks,
