Section 4 says
When the value of the EDNS(0) DE flag is 0, the server behaves as a
server that does not implement this specification, i.e., Delegation Types are
treated as Data Types.
Let's say I have this in my .EXAMPLE zone file:
foo.example. deleg server-ipv4=1.2.3.4
Then my dusty web server does an A request for foo.example. There's no NS
so there's no referral. But there's a DELEG record so it returns NOERROR.
That can't be right.
I think it needs to say something like when the DE flag is 0, delegation
types are ignored in queries other than explicit ones for the delegation
type itself and maybe ANY.
