The penultimate paragraph of https://tools.ietf.org/html/rfc7489#section-6.3 states: the "v" and "p" tags MUST be present and MUST appear in that order. While the v= tag pretty universally appears first, the p= tag does not in many records, and no implementation appears to care. The v= tag must appear first, or the policy discovery mechanism as defined in https://tools.ietf.org/html/rfc7489#section-6.6.3 would break. But there doesn't appear to be any real reason to keep the normative requirement that the p= tag MUST be second in the record after the v= tag, nor does this requirement seem to have any impact on interoperability or general record parsing in theory or in practice. Should we remove this normative requirement? -- *Seth Blank* | VP, Standards and New Technologies *e:* [email protected] *p:* 415.273.8818 This email and all data transmitted with it contains confidential and/or proprietary information intended solely for the use of individual(s) authorized to receive it.
