Hi
I can answer the following 2 minor points:
- S2.1.1.3.1.1: "Value ?0" --> should it be "Value 00"?
`?0` means it can be either `10` or `00`.
Aka, only the last bit `0` matters.
- S2.1.1: The value of the magic number: 0xFD2FB528 --- is there any
significance to it?
This value was selected to be less probable to find at the beginning of some
random file.
It avoids trivial patterns (0x00, 0xFF, repeated bytes, increasing bytes, etc.),
contains byte values outside of ASCII range,
and doesn't map into UTF8 space.
It reduces chances that a text file be able to represent this value by accident.
For all other points, I have no comment, and agree with reviewer.

Summary: Ready with 1 minor issue and some nits.
Major issues: 0
Minor issues: 2
Nits/editorial comments: 3
Minor:
- S4: "... and the usual precautions apply." Here, what are the "usual
precautions"? Are they the ones enumerated below? If so, then
perhaps restate as "... and the usual precautions apply, as enumerated
below.".
If the usual precautions are not enumerated below, then a reference should
be provided to a resource(s) that enumerates such precautions.
- S5: I am curious, why should we remove this section prior to publication?
It contains pointers to code that is invaluable to implementors. At the
most, I would advise excising company name (Facebook) from the section,
but I would advocate strongly to retain this section as the draft becomes
a RFC.
Nits/Typos:
- S2.1.1: The value of the magic number: 0xFD2FB528 --- is there any
significance to it? Any insight on how you arrived at this will be
interesting. (I am relating this magic number to the SIP magic cookie
"z9hG4bK" which was chosen so that the probability was very small of
older implementations to randomly pick a branch ID that started with
these characters.)
- S2.1.1: s/the origina/the original/
- S2.1.1.3.1.1: "Value ?0" --> should it be "Value 00"?
