Amanda, In the hope of getting something else on which I'm working [1] right, some questions about the above: If I look at a protocol assignments page, e.g., https://www.iana.org/assignments/mail-parameters/mail-parameters.xhtml is "MAIL Parameters" the "top-level registry" aka "registry group", despite the fact that some of the registries on that page are associated with different protocols (even if they are somehow mail-related and, as we have discussed, there are mail-related registries elsewhere)? Also some of what I assume are called "registries" ("SMTP Service Extensions", "SMTP Service Extension Parameters", "Mail Transmission Types", etc.) are subsidiary to other ones there. Does that make a difference? And, is "SMTP Service Extension Parameters" properly a sub-registry of "SMTP Service Extensions"? And, forgive my ignorance, but what is a "TLV" in this context? thanks, john [1] draft-ietf-emailcore-rfc5321bis -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
