<div>The problem is you can't NSEC3 with a NSEC-only key, but you can
NSEC with an NSEC3-capable key.</div>

I made the same mistake when I tried this the first time.</div>

<div>Am I doing something wrong in step 5 or is it not possible to do
(5)?</div>
<div>With step 4, I got a signed domain inline with what you have
attached in your email.</div>
<div><br></div>
<div>So - alg 5 and/or 7 can be in a NSEC zone</div>
<div>Only alg 7 can be in a NSEC3 zone</div>
<div><br></div>
<div>The reason is that if a validator only knows alg 5, it probably
doesn't understand NSEC3 so it would have issues.</div>
<div><br></div>
<div>If a validator knows alg 7, it knows NSEC (from the old days) and
NSEC3 (the new thing).</div>

<div>that they're not getting traction.</div>
