Mapping the .xsl extension to asp.dll seems confusing to me. What you are
attempting to do is to pass parameters to the XSL stylesheet. The most
efficient way to do this is to pass parameters as top level attributes of
the XML document itself e.g.:

	var str = objXML.transformNode(objXSL);

This allows the client to cache the XSL stylesheet, eliminates the overhead
of server processing and eliminates the network roundtrip associated with
the transformation.

You can use XSL conditionals such as
<xsl:if test=".[@color = 'red']">
<xsl:choose><xsl:when test="/*[@language='italian']">

to do this.

Using XSL and client side transformation, I have been able to greatly reduce
the need to use ASP, saving this for appropriate uses such as database
access/updates and other transactions.
