That should be a little more precise.
TCP packets can not (for all practical purposes when dealing with "normal"
clients) be self contained.
UDP packets are self contained, from the network view.
But that does not mean that a particular protocol implemented on top of
UDP will necessarily still be self contained, merely that it is possible
for it to be.
