title: Xalan date extension problem
body: <p>i'm trying to use the ubuntu cli version of xalan:</p>
  
  <pre><code>Xalan version 1.10.0
  Xerces version 2.8.0
  </code></pre>
  
  <p>My problem is how to kick in with date functions. I tryed like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;xsl:stylesheet version="1.0"
                  xmlns:xs="http://www.w3.org/2001/XMLSchema"
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                  xmlns:date="http://exslt.org/dates-and-times" extension-element-prefixes="date"&gt;
  
  &lt;xsl:import href="date/date.xsl" /&gt;
  &lt;xsl:output method="text" indent="yes" /&gt;
  date: &lt;xsl:value-of select="date:date()" /&gt;
  &lt;/xsl:stylesheet&gt;
  </code></pre>
  
  <p>It gives me back this message:</p>
  
  <pre><code>XSLException Type is: XalanXPathException
  Message is: The function number 'http://exslt.org/dates-and-times:date' is not available. (file:///home/user/test.xsl, line x, column y)
  </code></pre>
  
  <p>What files or what do i need to change to make those date functions work?</p>
