"In-bailiwick" means that the nameservers for a zone are under the apex of that zone. So the uk TLD servers are in-bailiwick: they are all of the form nsX.nic.uk for various X. The com TLD servers are not in-bailiwick since they are all under gtld-servers.net; similarly the .aero servers are under .de, .ch, .info, .org. If a zone has in-bailiwick nameservers then it must have glue in the parent zone. It is possible for a TLD to have no glue of its own (like .com) if all of its nameservers are under other TLDs. It is possible for a TLD to have no glue at all if it shares no nameservers with any other TLD - so .com has glue (shared with .net) but the .aero nameservers are all under other TLDs and are different from those TLDs' servers, so it can work without glue.
