Use of global variable and parameter

["Vivek Shinde" <Vivek.Shinde@xxxxxxx>]

Hi,

I have first XSL as follows: 

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
	<xsl:output method="html"/>

	<xsl:variable name="forcountry" select="GB"/>
	<xsl:include href="secondxsl.xsl"/>

</xsl:stylesheet>

Then withing secondxsl.xsl I am using a variable 'forcountry' within one of the template as:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
	<xsl:output method="html"/>

<xsl:template match="article" mode="details-introduction">
<xsl:if test="metadata[countryname=$forcountry]">
..........
..........
</xsl:if>
</xsl:template>
</xsl:stylesheet>

But, it seems that the value of forcountry is blank within secondxsl.xsl.
I understand that the global variable definition works only within a stylesheet (I tried defining xsl:variable within the secondxsl.xsl right after xsl:output and it still does not work). But in Michael Kay's book 'XSLT 2nd edition' on page 83 it states 'Global parameters are set from outside the stylesheet' (last paragraph), so I tried changing 'xsl:variable' to 'xsl:param' and it still does not work.

Any help please?
Thanks
Vivek
