We're using XALAN. I've downloaded the date.zip file
(http://www.exslt.org/date/date.html), but do I need to extract all
that and put it in a related path to the stylesheet? I'm getting IO
errors, and I probably need to resolve the hierarchy if needed.
Are you suggesting below that the processors have the functionality
already built in, and I should be able to use the element definitions
without importing?

i.e.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="date">
<xsl:import href="date/date.xsl" />

<xsl:template match="/">
<xsl:element name="dynamiclongvalue"><xsl:value-of
select="date:year"/></xsl:element>

</xsl:stylesheet>

OR

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="date">

<xsl:template match="/">
<xsl:element name="dynamiclongvalue"><xsl:value-of
select="date:year"/></xsl:element>

</xsl:stylesheet>


Well.... I just tried it, and XALAN supports the date:year function
