In XSLT, as in other programming languages, typing can be very useful. I personally have already benefitted by XSLT 2.0 typing. In particular, it allows me to eliminate code, which in XSLT 1.0 was necessary, e.g. to check if a node-set passed as parameter is empty and then issue an error message: Instead of: <xsl:template name="foldl1"> <xsl:param name="pFunc" select="/.."/> <xsl:param name="pList" select="/.."/> <xsl:choose> <xsl:when test="not($pList)"> <xsl:message terminate="yes">Some strong words!!!</xsl:message> </xsl:when> <xsl:otherwise>useful code here</xsl:otherwise> I now can simply write: <xsl:function name="f:foldl1"> <xsl:param name="pFunc" as="element()"/> <xsl:param name="pList" as="item()+"/> <!-- useful code here --> This is a significant reduction of the complexity of the code and the total number of lines. As result the code is simpler, more easier to write and understand, programmer productivity is increased. ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL __________________________________ Do you Yahoo!?
