Come to think of it, I'm wondering what difference the intermediate variable

<xsl:variable name="somevar" select="node()" />

<xsl:for-each select="../element">
  <xsl:apply-templates select="$somevar">
    <xsl:with-param name="p" select="." />


<xsl:for-each select="../element">
  <xsl:apply-templates select="../body/node()">
    <xsl:with-param name="p" select="." />

My inclination would be to assume that in the latter the expression
'../body/node()' would be evaluated for each ../element, where in the first
case the corresponding expression from a different context would be
evaluated only once, and the result is then readily available as a literal
for the context of the xsl:for-each. (making the first the better option
only in cases where the node-set is small but the expression to match it is

Anyone to confirm/reject this assumption?
