passing parameter to template with using document()

Hi all,

I am having a problem with passing a paramter to template. It works without 
using document(). Do you know how to code it working with using document()? 

This is code which has no value pass into template. Anything I am doing wrong?  
 Thanks!

<xsl:for-each select="tech">
        <xsl:variable name="current-tech" select="@descr"/> 
        <xsl:apply-templates select="document('report.xml')" mode="report">
                <xsl:with-param name="current" select="$current-tech"/>
        </xsl:apply-templates>
</xsl:for-each>

<xsl:template match="item" mode="report">
<xsl:param name="current" />
        <xsl:if test="($current = metadata/technology)">
                <xsl:value-of select="content/company/." /><br/>
        </xsl:if>
</xsl:template>
