WMS DriverThe web map service driver extends abstracts WxS driver with the getMap feature.NodesWmsServiceNodeRepresents the WMS service. This node has no attribute and
has as children WmsOperationNode like GetMap.
Others children give information about the service like layers, and are XmlNode.
Those children are filled in by the information returned from
the service's GetCapabilities request.WmsOperationNodeRepresents an operation than can mde on the service.
For WMS service, the mandatory operation are GetMap, GetCapabilities, and
GetFeatureInfo.
Optional operations may be provided by the service
and indicated in the possibilities thereof.
Those optional operations are also represented as WmsOperationNode.For perform an operation (mandatory or optional), you can use the operator '[]' with a dict that contains
the parameters of the request.Example:dict_request = {'layers': 'mgrs_region', 'format': 'image/png', 'height': 256, 'width': 256, 'crs': 'EPSG:3857', 'bbox': '7514065.628545968,7514065.628545967,10018754.171394622,10018754.171394628'}


get_map = service_wms['GetMap'][dict_request]For mandatory operations GetMap and GetFeatureInfo you can
alternatively use Predicate WmsGetMapPredicate and WmsGetFeatureInfoPredicate.Specific class define WXSNodeOperationGetMap and WXSNodeOperationGetFeatureInfo
for accept respectively WmsGetMapPredicate WmsGetFeatureInfoPredicate.Example:predicate = WmsGetMapPredicate(layers='mgrs_region', height=256, width=256, bbox='7514065.628545968,7514065.628545967,10018754.171394622,10018754.171394628'}
