</span>Ah, opt-out with empty non terminals. Tricky business. From that quote<br>
(and some light reading) I can not derive the signer output is wrong.<br>
Basically that requirement explicitly does not apply here.<br>
<br>
I'm unsure why validns does not detect the empty non-terminal. But I<br>
admit further reading might be necessary to give a definitive answer.<br>

It does not mean the ODS signer is doing the wrong thing, I only mention it as a reference to other interpretations on the RFC definition. Unfortunately the different interpretations break few of my tests on the signed zones which is not ideal. I presume in practice nothing will be broken in either way.</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><span class=""><font color="#888888">
