[xsl] Probably a very simple xsl:if question

Subject: [xsl] Probably a very simple xsl:if question

Hi,

I am trying to get an evaluation working with <xsl:if> which I think
should work, but obviously I am missing something very specific, which I
haven't been able to find in any of my books (Learning XSLT not XSLT and
XPath On The Edge) nor on the Internet.

So I appeal to you lot. :)

I got a simple xml file of the form:

<news>
  <entry>
    <date>2004-02-14</date>
    <content>It is Valentine's Day today</content>
  </entry>
</news>

Now, in my .xsl file I do the following (don't mind the HTML4, need to convert
it to XHTML still, I also left out the CSS):

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

  <xsl:output method="html" indent="yes"/>
  <xsl:output doctype-public="-//W3C//DTD HTML 4.01//EN"
    doctype-system="http://www.w3.org/TR/html4/strict.dtd"/>

  <xsl:template match="news">
    <exsl:document href="news.html">
      <xsl:variable name="now" select="date:date-time()"/>
      <html dir="ltr" lang="en">
        <head>
          <title>News</title>
	</head>

        <body>
	  <h1>News - <xsl:value-of select="date:year($now)"/></h1>

	  <p>News - <xsl:value-of select="date:year($now)"/></p>

	  <xsl:for-each select="entry">
	    <xsl:sort data-type="date" order="descending" select="date"/>
	    <xsl:variable name="
	    <xsl:if test="date:year(date) = $now">
	      <li>
	      <b><xsl:value-of select="date"/></b>: <xsl:value-of select="content"/>
	      </li>
	    </xsl:if>
	  </xsl:for-each>
	</body>
      </html>
    </exsl:document>
  </xsl:template>
</xsl:stylesheet>

In the <xsl:if test=""> case what I have now yields 0 (xsltproc) whereas
if I replace $now with 2004 it works.  What obvious little thing am I
missing/forgetting here?

Thanks,
