"final" response control data

[mnot]

Comment by @fpalombini

Section 3.5:

I see that the Section 3.5.1 talks about "final status code":

associated header section until the final status code is encoded.

and that explains why you called it "final" in section 3.5, but I think you need to define why "final" is used in the "final response control data" when it first appear (so in Section 3.5), or you can remove "final" in 3.5 and explain that only in 3.5.1.
