1. gSOAP 最新版本為 2.8.12, 此版本在 FAQ 中註明了 ONVIF 程式產生時的 define namespace prefix and type bindings，如此在開發程式時可有一個統一的命名規則。如下：
tds = "http://www.onvif.org/ver10/device/wsdl"
tev = "http://www.onvif.org/ver10/events/wsdl"
tls = "http://www.onvif.org/ver10/display/wsdl"
tmd = "http://www.onvif.org/ver10/deviceIO/wsdl"
timg = "http://www.onvif.org/ver20/imaging/wsdl"
trt = "http://www.onvif.org/ver10/media/wsdl"
tptz = "http://www.onvif.org/ver20/ptz/wsdl"
trv = "http://www.onvif.org/ver10/receiver/wsdl"
trc = "http://www.onvif.org/ver10/recording/wsdl"
tse = "http://www.onvif.org/ver10/search/wsdl"
trp = "http://www.onvif.org/ver10/replay/wsdl"
tan = "http://www.onvif.org/ver20/analytics/wsdl"
tad = "http://www.onvif.org/ver10/analyticsdevice/wsdl"
tdn = "http://www.onvif.org/ver10/network/wsdl"
tt = "http://www.onvif.org/ver10/schema"
