The original onvif module was NOT at all ONVIF protocol implementation.
This one pretty much copies the Netcat module but with a bit of clarity
to the XML that is sent to the camera but most importantly allows
specification of full onvif URL including authentication and control URI
through the Control Address field. Parsing of the url is done through a
combination of sane defaults and the URI module.
