Jeje,
Funny. In OGC they are also considering splitting WFS into several levels of complexity and to not force the use of GML, I wonder when they are going to start talking about WFS Lite.
Cheers.

Well,
Not quite a FULL WFS without transactions.
The WFS includes the capabilities and filter capabilities to allow servers to declare what the are capable of.
This means that servers can declare that they support very little. For example, the following filter capabilities:
<ogc:Filter_Capabilities xmlns:ogc="http://www.opengis.net/ogc%22%3E ogc:Spatial_Capabilities <ogc:GeometryOperands xmlns:gml="http://www.opengis.net/gml%22%3E ogc:GeometryOperandgml:Point</ogc:GeometryOperand> </ogc:GeometryOperands> ogc:SpatialOperators <ogc:SpatialOperator name="BBOX" /> </ogc:SpatialOperators> </ogc:Spatial_Capabilities/> ogc:Id_Capabilities <ogc:EID /> </ogc:Id_Capabilities> </ogc:Filter_Capabilities>
indicates that this server only supports BBOX on gml:Point types.
So the most complex request you could form (on as single feature type) would be something like:
http://www.server.com/wfs/wfs.cgi? service=WFS&version=1.1.0&request=GetCapabilities&typeName=myns:Points OfInterest&BBOX=10,10,20,20
I would prefer that this work (WFS Simple I mean) be rolled back into the WFS specification as a level 0 conformance class rather than having two independent specifications that do similar things ... even if this means making GML a preferred but not mandatory output format for the GetFeature operation.
The WFS already allows other formats, other than GML, to be supported so something like KML is well within the scope of the current spec..
Ciao.

In the WFS specification the idea of a 'Basic WFS' is mentioned that pertains to a full WFS that is read-only--no transactional support. This is quite different from the intent of this effort, so the working name has been changed to 'WFS Simple'.
