i tested your xsl with my xml(shown bellow)
your xsl with one change: <xsl:template match="//Item">
without the change there is no output, so i agree on that root element
can not access the variable
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="mode1" select="'1'" />
<xsl:variable name="mode2">1</xsl:variable>
<xsl:apply-templates />
</xsl:template>
<xsl:template match="//Item">
<html>
<body>
<xsl:if test="$mode1='1'">Mode 1 =
'1'</xsl:if>
<xsl:if test="$mode2='1'">Mode 2 =
'1'</xsl:if>
<xsl:if test="$mode2=$mode1">Mode 2 =
Mode 1</xsl:if>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
my xml
<?xml version="1.0" encoding="UTF-8"?>
<study>
<Item/>
</study>
here is the result
Mode 1 ='1'Mode 2 ='1'Mode 2 =Mode 1
but in my case it is a different story, i did not use apply-template,
instead, i use call-template.
i also tested with my xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="mode1" select="'1'"/>
<xsl:variable name="mode2" select="2"/>
<xsl:variable name="mode3">3</xsl:variable>
<xsl:call-template name="dosomething"/>
</xsl:template>
<xsl:template name="dosomething">
<xsl:if test="$mode1='1'">
<xsl:text>mode='1'</xsl:text>
</xsl:if>
<xsl:if test="$mode2='1'">
<xsl:text>mode=2</xsl:text>
</xsl:if>
<xsl:if test="$mode3='3'">
<xsl:text>mode=3</xsl:text>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
here is the output
mode='1'mode=3
so the template "dosomething" can access the variable set in template
which match "/"

NO!! You are both wrong.
This stylesheet will not work
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="mode1" select="'1'" />
<xsl:variable name="mode2">1</xsl:variable>
<xsl:apply-templates />
</xsl:template>
<xsl:template match="root">
<html>
<body>
<xsl:if test="$mode1='1'">Mode 1 =
'1'</xsl:if>
<xsl:if test="$mode2='1'">Mode 2 =
'1'</xsl:if>
<xsl:if test="$mode2=$mode1">Mode 2 =
Mode 1</xsl:if>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
It gives the error
Description: A reference to variable or parameter 'mode1' cannot be
resolved. The variable or parameter may not be defined, or it may not be
in scope.
Or
Failed to compile style sheet
At xsl:if on line 29 of _file:/C:/DOCUME~1/chris/LOCALS~1/Temp/[Input
XSL]: Variable mode1 has not been declared
Depending on the processor
