The module includes a fallback in case `xpath` fails due to a malformed `pidf-lo` (observed at ETSI Plugtests events). In such a case it just looks for attributes like `lat/lon` (point) or `lat/lon/radius` (circle) and creates a new location object, which I guess requires a `gml` namespace, therefore I would suggest the following change:
` if(loc->xpath == NULL) {xmlNewProp(ptrFindService, BAD_CAST "xmlns:p2", BAD_CAST "http://www.opengis.net/gml%22);%7D `
