Re: [DNSOP] I-D Action: draft-ietf-dnsop-extended-error-12.txt

[Tim Wattenberg <[e-mail]>]

(Sorry for the belated feedback.)

I was just reading the document to work on some early implementation during the Hackathon and noticed a small inconsistency:
Section 2 defines the wire-format and states for the OPTION-LENGTH it „[…] should be 4 plus the length of the EXTRA-TEXT section (which may be a zero-length string)“.
However, I think the length is meant to be *2* plus the length of the text and this is still a remnant of an earlier version.

For the sake of consistency, you might also think about using the „2-octets/16-bits“ notation for the INFO-CODE definition as well.
