 * Function: OpenLayers.Protocol.WFS.fromWMSLayer
 * Convenience function to create a WFS protocol from a WMS layer.  This makes
 *     the assumption that a WFS requests can be issued at the same URL as
 *     WMS requests and that a WFS featureType exists with the same name as the
 *     WMS layer.
 *     
 * This function is designed to auto-configure <url>, <featureType>,
 *     <featurePrefix> and <srsName> for WFS <version> 1.1.0. Note that
 *     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.
