[xsl] How do I pass params from <xsl:apply-templates> and receive params

How do I pass params from <xsl:apply-templates> and receive params from the 
template?

This is same problem as I posted in "Mapping from two sources". But I am trying 
different method of using <xsl:apply-templates> with param.

I need to have two sources:

input1 and input2. 

input1:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Order>
        <OrderLine>
                        <OLN>1</OLN>
                        <Fname>aa</Fname>
        </OrderLine>
        <OrderLine>
                        <OLN>2</OLN>
                        <Fname>bb</Fname>
        </OrderLine>    
</Order>


input2:
<?xml version="1.0" encoding="ISO-8859-1"?>
<POOrder>
        <POOrderLine>
                        <OLN>1</OLN>
                        <ID>123</ID>
                        <LName>aa</LName>
        </POOrderLine>
        <POOrderLine>
                        <OLN>2</OLN>
                        <ID>324</ID>
                        <LName>bb</LName>
        </POOrderLine>  
        <POOrderLine>
                        <OLN>3</OLN>
                        <ID>456</ID>
                        <LName>bb</LName>
        </POOrderLine>  
</POOrder>

I need the output from both sources combined. Please note that first two 
elements are coming from input1 and thrid element is from input2. What is the 
optimal way of doing this?

<?xml version="1.0" encoding="ISO-8859-1"?>
<OrderResponse>
        <Oline>
                <OLN>1</OLN>
                <Fname>aa</Fname>
                <ID>123</ID>
        </Oline>
        <Oline>
                <OLN>2</OLN>
                <Fname>bb</Fname>
                <ID>324</ID>
        </Oline>
</OrderResponse>

So I did the following:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
xmlns:fn="http://www.w3.org/2005/xpath-functions";>
        <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
        <xsl:template match="POOrder">
                <xsl:param name="param1"/>
                <xsl:param name="param2"/>
                <xsl:value-of select="$param1"/>  ==========> But I am not able 
to receive params that I am passing???
                <xsl:value-of select="$param2"/>
        </xsl:template>
        
        <xsl:template match="Order">
                <OrderResponse>
                        <xsl:for-each select="OrderLine">
                                <Oline>
                                        <xsl:apply-templates 
select="document('C:/temp/input2.xml')"/>
                                        <xsl:variable name="vOln">
                                                <xsl:apply-templates 
select="POOrder">
                                                        <xsl:with-param 
name="param1"><xsl:value-of select="OLN"/></xsl:with-param>
                                                        <xsl:with-param 
name="param2">OLN</xsl:with-param>
                                                </xsl:apply-templates>
                                        </xsl:variable>
                                        <OLN><xsl:value-of 
select="$vOln"/></OLN>
                                        <Fname><xsl:value-of 
select="Fname"/></Fname>
                                        <Email><xsl:value-of 
select="Email"/></Email>                   
                                </Oline>
                        </xsl:for-each>
                </OrderResponse>
        </xsl:template>
</xsl:stylesheet>
