A full sink requires you to register the sink and then manage it via the events API. You can attach it to event, detach, receive notifications of new events in the system and much more. The WinGate Policy Engine component is one such sink component. It dynamically attaches and detaches event sinks when users drop event sources into the various policies.
A minisink on the other hand is registered by the component and then the events system manages displaying and hooking the minisink to compatible events. You just need to supply a few functions via the EventMiniSinkEngineInterface and EventMiniSinkGUIInterface and the framework does the rest. There are of course limitations to minisinks and they are described more in the Minisinks section.
