Date Time Module Unknown Saxon extension element script

Hi All,

I'm trying to implement the Date-Time extension, but I'm afraid my XSL
knowledge is at it's glass ceiling at the moment.

I'm working from this reference doc:
http://www.exslt.org/date/functions/month-in-year/index.html

So far, I've downloaded and installed the Date-Time Functions.

I want to insert a date-time into an existing XSL sheet called
InlineCustomization.xsl

At the top of InlineCustomization.xsl, I've added:

<xsl:stylesheet 
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
	xmlns:encoder="xalan://java.net.URLEncoder"
exclude-result-prefixes="encoder" 
	xmlns:date="http://exslt.org/date"
	xmlns:func="http://exslt.org/functions" 
	extension-element-prefixes="date func">
	<xsl:import
href="http://www-dev.sheridan.edu:8080/uPortal/media/edu/vt/portal/layou
t/TabPageColumn/InlineCustomization/XSL/functions/month-in-year/date.mon
th-in-year.xsl" />
	<xsl:import
href="http://www-dev.sheridan.edu:8080/uPortal/media/edu/vt/portal/layou
t/TabPageColumn/InlineCustomization/XSL/functions/month-in-year/date.mon
th-in-year.function.xsl" />
		

I'm getting this error when I try to do a local transform in Oxygen
using Saxon Transformer 6.5.4:

"Error: Unknown Saxon extension element script"
