The variable item-elements is the root node of a temporary tree, and when
you apply-templates to it, the template rule invoked is the one with
match="/". Use apply-templates select="$var/*", or use a mode.
Note that Saxon 6.5 does not correctly enforce all the restrictions in the
XSLT 1.0 specification, which prevent you using a result tree fragment as a
node-set in this way.

Subject: [xsl] Select on Node List Variable
I am having trouble understanding the behavior of the
following stylesheet.
I intended for the main template to build a node-list of
<item> elements and
then process them using another template, but instead Saxon
6.5.2 is giving
me a stack overflow error. If I change the 'apply-templates' and
corresponding template to use a mode, it works as intended
(outputs 'hello'
and 'goodbye').
<?xml version="1.0" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"
standalone="no"/>
<xsl:template match="/">
<xsl:variable name="item-elements">
<xsl:element name="item">hello</xsl:element>
<xsl:element name="item">goodbye</xsl:element>
</xsl:variable>
<xsl:apply-templates select="$item-elements"/>
</xsl:template>
<xsl:template match="item">
<xsl:value-of select="."/>
<xsl:if test="position() != last()">
<xsl:text> </xsl:text>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Why the infinite loop?
