It seems to me the test might be easier if you declared, instead of snode:

 <xsl:variable name="snode-id" select="generate-id((//Menu)[number($pos)])"/>

and then your node identity test could be

<xsl:when test="generate-id() = $snode-id">
  (get the document() nodes ... )
</xsl:when>

which would be faster, I bet.

Cheers,
Wendell
