Rick,
Think on second group you want <xsl:for-each-group select="current-group()/*">
Try this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema"; exclude-result-prefixes="xs"
version="2.0">
<xsl:output indent="yes"/>
<xsl:template match="/">
<xsl:result-document href="rick-output.xml">
<xsl:apply-templates/>
</xsl:result-document>
</xsl:template>
<xsl:template match="root">
<root>
<xsl:for-each-group select="*"
group-adjacent="
if (self::topic) then
1
else
0">
<xsl:choose>
<xsl:when test="current-grouping-key() = 1">
<ol>
<xsl:for-each-group select="current-group()/*"
group-adjacent="
if (self::subtopic) then
1
else
0">
<xsl:choose>
<xsl:when test="current-grouping-key() = 1">
<ul>
<xsl:apply-templates
select="current-group()"/>
</ul>
</xsl:when>
<xsl:otherwise>
<li>
<xsl:apply-templates
select="current-group()"/>
</li>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</ol>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</root>
</xsl:template>
<xsl:template match="topic | subtopic">
<li>
<xsl:apply-templates/>
</li>
</xsl:template>
<!-- Identity transform. -->
<xsl:template match="@* | node()">
<xsl:copy copy-namespaces="no">
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Hi,
Alternatively, if you wish to continue using xsl:apply-templates
idiomatically and capture all nodes in traversal without the ungainly
"current-group()/node()", you could write
<xsl:for-each select="current-group()">
<xsl:apply-templates/>
</xsl:for-each>
This does something slightly different in the presence of comments and
processing instructions i think. THe coffee hasn't worked here yet.
Also, Rick already has <xsl:apply-templates select="current-group()">
elsewhere in their XSLT :)
