OpenLayers.Layer.GML

Create a vector layer by parsing a GML file. The GML file is passed in as a parameter. Deprecated. To be removed in 3.0. Instead use OpenLayers.Layer.Vector with Protocol.HTTP and Strategy.Fixed. Provide the protocol with a format parameter to get the parser you want for your data.
