[Geoserver-users] wfs call to retrieve features from several layers: how to know what geometric object comes from what layer?

Dear experts,
I make a wfs call with some CQL filter to several layers and it creates a json with all the features for all returned geometric objects(linestrings in my case).
https://url:port/geoserver/wfs?service=wfs&version=1.0.0&request=GetFeature&typeName=cite:layer1,layer2,layer3&CQL_FILTER=filter1;filter2;filter3&outputFormat=json
It also returns some other non-geometric properties.
However, I can not see from the returned json what object comes from what layer. Is it easy to add that info in the call?
I am contemplating adding a field attribute layer_type. But this would then have a constant value for all records in the layer (for layer1: layer_type=1, layer2: layer_type=2, layer3:layer_type=3) which sounds a bit silly.
Is there any way of adding the layername where the geometric object came from to the response?
Thanks!

Hi,

Does the data look easier to parse in GML format? WFS is written for GML and it is hard to support all the flexible possibilities of GML in GeoJSON.
