True, but in this case, x seems to be evaluated twice:

<xsl:template match="/">
<result>

<xsl:call-template name="test"/>
</result>
</xsl:template>
<xsl:template name="test">

</xsl:stylesheet>
Explaining to people why that's legal, after telling them they can only
assign x once, is a nice challenge :)
