        <!-- 2 -->

                <xsl:param name="lastpos" />
                <xsl:message>b->lastpos '<xsl:value-of 
select="$lastpos"/>'</xsl:message>
                <xsl:message>b->position() '<xsl:value-of 
select="position()"/>'</xsl:message>
        </xsl:template>
</xsl:stylesheet>

Explanation:
When parameter is passed from template [1] to template [2], value of position()
function is calculated as 0, which is wrong. When $position is used instead of
position() in with-param select expression, correct value is passed to the
template [2].

This behaviour is specific to version 2.2.0 and all this worked fine in 2.1.0.
