Yes, since we’re obsoleting it there’s no need for the “Updates to” / “Update” 
words.

This sentence should be taken out of the source code, so I guess that means 
there’s two blocks of source code.

I think that’s right. The 255 bytes needs to include everything that is listed 
there.

GREAT CATCH! 

Definitely needs to be “producedAt”!

I prefer option A.

I will defer to my co-authors on this one.

I will put this on my to do list ;)

Yes please drop the extra “protocol” where appropriate.

I am happy with that.

So this is a bit weird maybe:

s3.2.2:

OLD:

authorityInfoAccess
   (AIA) extension nor cRLDistributionPoints (CRLDP) extension

NEW:

 Authority Information Access
   (AIA) extension nor CRL Distribution Points (CRLDP) extension

S4.1:

OLD:

authorityInfoAccess extension

NEW:

AIA extension

OLD:

authorityInformationAccess (AIA) extension
cRLDistributionPoints extension

NEW:

AIA extension
CRLDP extension

I am fine with changing it to on-path if my co-authors are.
