As you pointed out, the protocol, if properly implemented, addresses this. There should always be Glue (A records for the NS) in a delegation. RFC 1034 even specifies this: 4.2.2 <snip> As the last installation step, the delegation NS RRs and glue RRs necessary to make the delegation effective should be added to the parent zone. The administrators of both zones should insure that the NS and glue RRs which mark both sides of the cut are consistent and remain so. </snip>
A probably important distinction: That's not the protocol, that's the specified implementation framework of the protocol. In general, DNS still works if you screw that up, which is why it's so often screwed up. Cheers, -- jra -- Jay R.
