Barry Leiba has entered the following ballot position for draft-ietf-lamps-rfc6844bis-06: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-lamps-rfc6844bis/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- — Section 4.1 — Tag Length: A single octet containing an unsigned integer specifying the tag length in octets. The tag length MUST be at least 1 and SHOULD be no more than 15. What happens if it’s more than 15? What’s the interoperability issue, and how would an implementor decide what to do with this requirement? Tags MAY contain US-ASCII characters 'a' through 'z', 'A' through 'Z', and the numbers 0 through 9. Tags SHOULD NOT contain any other characters. Matching of tags is case insensitive. Why “SHOULD NOT”, rather than “MUST NOT”? Why might my implementation need to use other characters, and what are the interoperability consequences of doing so? — Section 4.1.1 — Tag: Is a non-zero sequence of US-ASCII letters and numbers in lower case. Make it “non-zero-length”. -- Section 4.4 — The iodef Property Tag takes a URL as its Property Value. The URL scheme type determines the method used for reporting: I presume that *only* the specified schemes (mailto, http, https) are allowed; it would help to be explicit about that, lest someone get ideas to use sip or some such. — Section 5.6 — In practice, such an attack would be of minimal effect since any competent competitor that found itself unable to issue certificates due to lack of support for a Property marked critical SHOULD investigate the cause and report the reason to the customer. The customer will thus discover that they had been deceived. This doesn’t strike me as a BCP 14 “SHOULD”, but a normal English “should”.
