[xsl] XSLT 2.0 and lazy evaluation

[Jose Emilio Labra <jelabra@xxxxxxxx>]

Does XSLT 2.0 implement lazy evaluation?

I ask this because the following example returned 4 in
XSLT 1.0 but generates an error in XSLT 2.0
processors.

<xsl:stylesheet
       
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
        version="2.0">

<xsl:template match="/">
 <xsl:call-template name="f">
  <xsl:with-param name="x" select="2" />
  <xsl:with-param name="y" select="3 div 0" />
 </xsl:call-template>
</xsl:template>

<xsl:template name="f">
 <xsl:param name="x" />
 <xsl:param name="y" />
 <xsl:value-of select="$x + $x" />
</xsl:template>

</xsl:stylesheet>
