Hi all,
For those who do want support for GML 3.2.1 but don't want to hack OpenLayers,
here is an override function you can use (thanks to BartvE)
OpenLayers.Util.extend(OpenLayers.Format.WFST.v1_1_0.prototype.namespaces,
{gml32: "http://www.opengis.net/gml/3.2"});
OpenLayers.Util.extend(OpenLayers.Format.WFST.v1_1_0.prototype.readers,
{"gml32": OpenLayers.Format.GML.v3.prototype.readers["gml"], });
