What is different about a path with a single variable, and a path with

<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.
Minor follow-up, for XPath language lawyers who care:
In XPath 2.0, $node/$branch/leaf is legal, though deserving of at least a
warning (again, assuming $node and $branch represent nodesets). What it does
is effectively ignore $node and return the leaf children of $branch.
Thanks to Michael Kay for pointing this out in a previous message.
