Thanks for bringing this back. I like the simplification with the
removal of the wild section.

One comment,

[3.1] As section 3 states that MIXFR is DNSSEC aware we need text
regarding NSEC3PARAM update as well.

For that I suggest to change 3.1 section name and include an extra
paragraph.

3.1 Implicit DNSSEC deletions

When an NSEC3PARAM is modified, the MIXFR client MUST also remove all
existing NSEC3 records on the zone.


One clarification question,

At 3.6, last paragraph, what is the practical case that a updated
record has an RDLENGTH of zero bytes?
