I'm not clear on the suggestion about MAY. We already present the choice; a MAY here would mean you can opt not to do any of these, which isn't redaction at all, and this whole memo doesn't apply.
"MAY choose A, B, or C" is not equivalent to "MAY choose A, B, C, or none of the above". For example, from RFC 5321:
Verbs and argument values (e.g., "TO:" or "to:" in the RCPT command and extension name keywords) are not case sensitive, with the sole exception in this specification of a mailbox local-part (SMTP Extensions may explicitly specify case-sensitive elements). That is, a command verb, an argument value other than a mailbox local-part, and free form text MAY be encoded in upper case, lower case, or any mixture of upper and lower case with no impact on its meaning. In this case, I'm not sure what opting to not do any of those might mean. On the other hand, I'm also fine with John Levine's suggestion: An implementation MAY choose any transformation that has a reasonably low likelihood of collision. pr -- Pete Resnick<http://www.qualcomm.com/~presnick/> Qualcomm Incorporated - Direct phone: (858)651-4478, Fax: (858)651-1102 _______________________________________________ marf mailing list [email protected] https://www.ietf.org/mailman/listinfo/marf
