> In a sense, a glue record with the same owner name as a zone cut could be equivalent to a glue record with an owner name that is subordinate to a zone cut. I don't have enough of the spec in my head to know why they would definitively be different from the protocol perspective. I realise it's not normal, but I don't know that it's prohibited.
