Hi,

I want to use <xsl:choose /> constructs in my rules.xml, but i'm getting an
XSLParseError.

Here's the traceback:

XSLTParseError: xsltParseStylesheetTop: unknown choose element

And Here is my rules.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<rules
    xmlns="http://namespaces.plone.org/diazo";
    xmlns:css="http://namespaces.plone.org/diazo/css";
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
    xmlns:xi="http://www.w3.org/2001/XInclude";>

    <xsl:variable name="frontpage"
                  css:select="body.section-front-page"/>

    <xsl:choose>
      <xsl:when test="$frontpage">
        <theme href="front-page.html" />
        <xi:include href="front-page.xml" />
      </xsl:when>
      <xsl:otherwise>
        <theme href="index.html"/>
        <xi:include href="adminrules.xml" />
      </xsl:otherwise>
    </xsl:choose>
</rules>


Is it possible to use <xsl:choose /> in rules.xml to easily make special
rules for front-page, news, and so-on? if not, why?
