Accessing Variable within a Variable

Hi!

I am doing the following -

<xsl:template name="Process">
<xsl:param name="X1" ></xsl:param>
<xsl:param name="X2" ></xsl:param>

<xsl:variable name="merger">
	<xsl:value-of select="$X1"/>
	<xsl:value-of select="$X2"/>
</xsl:variable>

<xsl:for-each select="$merger/item">
<xsl:choose>
	<xsl:when test="$X1/item = 'someValue'">do should
check in X1</xsl:when>
	<xsl:when test="some condition">this should check
condition in merger</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:template>

When I try this, I am getting the TRUE to the
condition $X1/item = 'someValue' condition even if
'someValue' is in $merger and not in $X1.

Can't I access $X1 like this while traversing $merger
with for-each?

Thanks in advance.
