[Tilecache] wms_name

[Aníbal Pacheco]

Hello list, setting up tilecache with CGI was out-of-the-box, great!.
But now I have a problem trying to map a WMS layer defined in mapserver 
to tilecache, the layer takes several layers from a WMS service.

Here is the definition in the .map:

LAYER
      NAME "argentina_brasil"
      TYPE POLYGON
      STATUS ON
      CONNECTIONTYPE WMS
      CONNECTION "http://somedomain.com/somepath/WMSServer"
      METADATA
          "DESCRIPTION" "Argentina_Brasil"
          "wms_srs" "EPSG:32721"
          "wms_name" "2,3,12,13"
          "wms_server_version" "1.1.1"
          "wms_format" "image/png"
      END
END


The wms_name is the problem, how to write that in the tilecache conf?

Thanks
