Would you have a more specific suggestion on how the definition should
be clarified? P802.11az/D2.6 defines the subfield to have "0 or 2" as
the length and uses following language to describe it: "Comeback After
subfield shall not be present (i.e. zero octets) in PASN authentication
frames from a non-AP STA."
That "shall" word is not appropriate in Clause 9, so this should be
cleaned up anyway. It might also be clearer to talk about the first and
third PASN Authentication frame instead of "from a non-AP STA"
especially in this Clause 9 that is supposed to describe the frame
format and not behavior. If you have some ideas on how this would be
easier to notice and understand, I can request this to be modified once
D3.0 goes out to a ballot.
