Re: [Acme] [Technical Errata Reported] RFC9115 (7336)

Carsten is obviously right.

I had missed the parenthetical in § 3.8.3.1. of RFC8610:

Thanks for spotting it!

Cheers, t

This is hilarious — the errata reporting form apparently ate my double backslashes.

Here is the corrected Corrected Text:

  oid = text .regexp "([0-2])((\\.0)|(\\.[1-9][0-9]*))*”

And here is how I would write this, having been bitten by backslashes in RFCs before:

  oid = text .regexp "([0-2])(([.]0)|([.][1-9][0-9]*))*”

(Actually, I would write this:

  oid = text .regexp "[0-2]([.](0|([1-9][0-9]*)))*”

…but this is a style issue.)
