+/**
+ * Function: fromWMSLayer
+ * Convenience function to create a WCS protocol from a WMS layer.  This makes
+ *     the assumption that a WCS requests can be issued at the same URL as
+ *     WMS requests and that a WCS featureType exists with the same name as the
+ *     WMS layer.
+ *     
+ * This function is designed to auto-configure <url>, <featureType>,
+ *     <featurePrefix> and <srsName> for WCS <version> 1.1.0. Note that
+ *     srsName matching with the WMS layer will not work with WCS 1.0.0.
+ * 
+ * Parameters:
+ * layer - {<OpenLayers.Layer.WMS>} WMS layer that has a matching WCS
+ *     FeatureType at the same server url with the same typename.
+ * options - {Object} Default properties to be set on the protocol.
+ *
+ * Returns:
+ * {<OpenLayers.Protocol.WCS>}
