I tried:
                                              <xsl:if
test="exists($productid)">
					   <Attribute name="PRODUCTID"
type="string"><xsl:value-of
select="$productid"/></Attribute>
					</xsl:if>

but got the following error:
06:47:27.062 global (ERROR) - Uncaught Exception:
'exists' is not a valid XSLT or XPath function.

-->exists($productid)<-- (line: 27, file:
file://C:\tibco\gi\3.1\GI_Builder.hta)
    at jsx3.xml.Processor.transform()
    at jsx3.xml.Entity.transformNode()
    at buildquery()
    at eg.service#callRouteAction()

I will try your suggestion.  Thanks for your reply.
