I tried using all three method, in both the chapter and sect1 sections.  The
result is that when clause catches EVERY element.  I am guessing it is
because there is a for-each statement above it, albeit on the other side of
a template, which is causing there to never be a following::node().
Specifically, it looks like (apologies if this wraps horribly):

...
<xsl:for-each select="book/chapter">
	<xsl:call-template name="desktop-control"/>
</xsl:for-each>
...

<xsl:template match="chapter" name="desktop-control">
	<xsl:variable name="chNum" select="position()"/>
	Creating Desktop Chapter <xsl:value-of select="$chNum"/>
	<xsl:variable name="chFileName">
		<xsl:value-of select="$desktopOut"/>/chap<xsl:value-of
select="$chNum"/>.html</xsl:variable>
	<redirect:write select="$chFileName">
		<xsl:apply-templates select="$chapterTemplate/*">
			<xsl:with-param name="chapter" select="."/>
			<xsl:with-param name="chNum" select="$chNum"/>
			<xsl:with-param name="tree" select="chapter"/>
		</xsl:apply-templates>
	</redirect:write>
</xsl:template>

<xsl:template match="call:insert[@id='NavbarDesktop']"> <!-- this is some
tag within the chain -->
	<xsl:param name="chapter"/>
	<xsl:param name="chNum"/>
	<xsl:choose>
		<xsl:when test="$chNum=1">[ <a href="index.html">Table of Contents</a> |
<a>
				<xsl:attribute name="href">chap<xsl:value-of select="$chNum
+1"/>.html</xsl:attribute>
				<xsl:value-of select="$source/book/chapter[position()=$chNum
+1]/title"/>
			</a> ]</xsl:when>
		<xsl:when test="not(following::chapter)">[ <a>
				<xsl:attribute name="href">chap<xsl:value-of
select="$chNum -1"/>.html</xsl:attribute>
				<xsl:value-of
select="$source/book/chapter[position()=$chNum -1]/title"/>
			</a> | <a href="index.html">Table of Contents</a> ] </xsl:when>
		<xsl:otherwise>[ <a>
				<xsl:attribute name="href">chap<xsl:value-of
select="$chNum -1"/>.html</xsl:attribute>
				<xsl:value-of
select="$source/book/chapter[position()=$chNum -1]/title"/>
			</a> | <a href="index.html">Table of Contents</a> | <a>
				<xsl:attribute name="href">chap<xsl:value-of select="$chNum
+1"/>.html</xsl:attribute>
				<xsl:value-of select="$source/book/chapter[position()=$chNum
+1]/title"/>
			</a> ] </xsl:otherwise>
	</xsl:choose>
</xsl:template>

Am I correct in saying that the problem is the for-each?  If so, what is the
recommended way to either circumvent it or use some other method that does
not chop up the tree?
