The leaf category can be used for interfaces of HNCP devices on which
it doesn't which to speak HNCP, e.g. where only non-HNCP devices
are expected to be, e.g. a WiFi AP for clients. The point is to not speak
 HNCP if you don't have to which can increase security (see 12.2).

"Endpoint" is used and defined in DNCP, I called it "DNCP Endpoint"
to indicate it comes from that draft, however i can remove the "DNCP"
if that would make it more clear.
