Re: combining two variables to generate XPATH

What is different about a path with a single variable, and a path with two variables? Why can't I specify a second variable:

<xsl:template name="foo">
 <xsl:param name="node"/>
 <xsl:param name="branch" select="'someBranch'"/>
 <xsl:for-each select="$node/$branch/leaf">
   <xsl:value-of select="@id" />
 </xsl:for-each>
</xsl:template>

This is not legal. The only place a variable reference can appear in a Path Expression is at the beginning. $node is OK here, but $branch is not.
