Yes, like I said, I would like to have this line deleted in section 6:

  "A parent MUST NOT perform a consistency check between CDS and
   CDNSKEY (other than for informational / debugging use) resource
   records."

That's not protocol, but prescriptive language that a parent is
disallowed to have a policy to verify the records.

I also think the line just above that:

  "The parent MUST choose to accept either CDS or CDNSKEY resource
   records (based upon local policy), and MUST NOT expect there to be
   both."

is mixing up 2 things:
- -What the parent -accepts-
- -What the parent -uses- when both are present.

I think it's perfectly fine for a parent to accept both, but it must
state which it will use when it sees both in the zone to manage
expectancy.

So suggested text to replace that with:

"The parent MUST choose to use either CDNSKEY or CDS resource records
as their default updating mechanism.
The parent MAY only accept either CDNSKEY or CDS, but it MAY also
accept both, so it can use the other in the absence of the default
updating mechanism, but it MUST NOT expect there to be both."
