DWidth request

[Miguel Gonçalves]

Hello,

I am using MapServer 4.6 for windows.
I am performing the following DWidth request to the layer cities of my 
map object.

http://localhost/cgi-bin/mapserv.exe?VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&MAP=../MAPS/tutorial/europe_1.map&Filter=
<Filter>
    <DWithin>
        <PropertyName>Geometry</PropertyName>
        <gml:Point>
            <gml:coordinates>-8.418000,41.539600</gml:coordinates>
        </gml:Point>
        <Distance units='m'>1000</Distance>
    </DWithin>
</Filter>


I also perform another request for the layer mjroads.

I would like to perform both requests at the same time but,
when I do "TYPENAME=cities,mjroads" I am only obtaining the results 
referent to the cities layer.
Is it illegal to use two layers in this type of requests?
Can anybody help me?
Thanks.
Best regards.
Miguel
