In answer to the question in the subject line,
in order for an XSL stylesheet to read request parameters in cocoon,
you have to set up the sitemap to make that possible.
You can do this a few different ways. The easiest is:

1) In your map:transform element, use use-request-parameters:

  <map:transform src="foo.xsl">
    <map:parameter name="use-request-parameters" value="true" />

(assuming your default transformer is XSLT)

Then every request parameter, such as L1 in your example, will
be passed to the parameter in the stylesheet of the same name,
e.g. <xsl:param name="L1" />
And when you reference the param as "$L1" in your stylesheet,
the value will be 'util'.

for a slightly different way to do this.
