* WMS requests and that a WFS featureType exists with the same name as the

|
* srsName matching with the WMS layer will not work with WFS 1.0.0..

* Parameters:
|
|
* layer - {<OpenLayers.Layer.WMS>} WMS layer that has a matching WFS
|
|
* FeatureType at the same server url with the same typename.
|
|
* options - {Object} Default properties to be set on the protocol.
