We then had a discussion if this should synthesised automatically and if this should be part of the spec and we said that this is implementation dependant and we should not describe it.

Yes, but the question was not about DELEG. There's no proposal to change the behavior you described.

The question was whether it should be made "possible to define new parent-side types that work with NS" (à la DS). DELEG may not need this, but perhaps something else.

It doesn't seem expensive to designate some part of the rrtype space for such use. For example, we could take the ranges currently anticipated in the draft OR'ed with the 0x200 bit (so we get 0xF200..0xF3EF public and 0xF3F0..0xF3FF private).

Best,
Peter
