| * Function: OpenLayers.Protocol.WFS.fromWMSLayer | |
| * Convenience function to create a WFS protocol from a WMS layer. This makes | |

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

| * 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. | |
