(Source:
http://www.xslt.com/html/xsl-list/2005-03/msg00423.html) Using the exslt functions in xslt 1.0 is not very hard. Here's what to do:
1) download the date and numerical format material from exslt.org
2) Put the following attribute in your xsl:stylesheet root element:
xmlns
ate="http://exslt.org/dates-and-times";
3) put the following include at the top level of your document (right after the root element).
<xsl:include href="path-to-installed-the-exslt-elements/date.xsl" />
4) Add the function to your sheet where you want it to appear:
<xsl:choose>
<xsl:when test="function-available('date
ate-time')">
(<xsl:value-of select="date
ate-time()"/>
</xsl:when>
<xsl
therwise>
</xsl
therwise>
</xsl:choose>
The only problem I had when I did this, was there was a bad include in one of the exslt stylesheets (it was looking in the wrong directory for a padding stylesheet). It wasn't hard to fix, though.
