Passing map:generate parameters to a XQuery

[thomas.0007]

Dear all,

I have a question about how to pass parammeters to a XQuery when called from
a Cocoon pipeline.

Let see an example how this is done with XSP pages:
<map:match pattern="*/*/*/*/report.html">
   <map:generate type="serverpages" src="docs/getPostcodeData.xsp">
      <parameter name="postcode" value="{1}{2} {3}{4}"/>
   </map:generate>
   <map:transform src="stylesheets/html/report.xsl"/>
   <map:serialize/>
</map:match>

In the XSP page there will
be:<xsp:expr>parameters.getParameter("postcode")</xsp:expr>
 If I use XQuery to generate the data:   <map:generate type="xquery"
src="docs/getData.xq">
        <parameter name="param1" value="{1}"/>        <parameter
name="param2" value="{2}"/>        <parameter name="param3" value="{3}"/>
<parameter name="param4" value="{4}"/>
   </map:generate>
then how do I access the parammeters from getData.xq?Regards,Thomas

eg

declare namespace request="http://exist-db.org/xquery/request";

let $p:=request:get-parameter("postcode",())
