(RFC 1958 was published since RFC 3066??!!)
Look, the IESG chair is the list administrator for the IETF-language list, and a participant in its deliberations. If there has been a serious lacuna in process for moving this draft toward BCP, I think he would have mentioned it on the IETF-languages list a *long* time ago. It was the IESG that issued the Last Call announcement, not me, not the authors of the draft, not anybody else on the IETF-languages list. It appears that IESG *is* moving it through a process toward BCP, and one can only assume they feel their process is adequate and appropriate.

Eh???!! That is simply not true. RFC 3066 was developed with full awareness and consideration of all the usage scenarios for RFC 1766, which it replaced. RFC 3066 discusses various IETF and W3C protocols that use language tags. (Have you actually read RFC 3066?)
> (b) nor which authority would document their meanings (plural)
Eh???!! Section 2.2 clearly identifies the authorities that document the meanings of subtags. I have pointed out that there are aspects of meaning that it does not address (which, btw, are not easily resolvable), but that does not imply that RFC 3066 was published without consideration of what authorities document meanings.

If Romans had started speaking a variant of Londinium's language, the proposed draft could easily accommodate that situation. That is not pathological. A tag like "sr-Latn-CS-gaulish-boont-guoyu-i-enochian" is pathological. It most certainly *is* appropriate to identify what kinds of examples are or not valid, as we need to design for *valid* usage scenarios. For any given character set encoding standard, the fact that nonsense character sequences can be devised is not a determining factor in development of that encoding; the same is true here.

??? You want to incorporate these things into the draft, or into language tags themselves? The latter is either not necessary or not appropriate (language tags should *not* include anything to indicate destination). As for inclusion in the draft, the proposed draft is quite clear about source authorities for subtags and about conformance; destination is out of scope and irrelevant. Internationalization? These are symbolic identifiers; they are intrinsically not localizable. Icon support??? I haven't a clue what you're talking about!

??? If someone needs to tag content to distinguish a particular dialect, the proposed draft can easily accommodate that. If one wants to tag content for minor linguistic details ("this utterance was spoken by someone who has a cleft palatte, who was intoxicated at the time, and uses tag-question intonation"), it is a *non goal* of the proposed draft to accommodate that level of detail as it is not appropriate to try to capture that level of ad hoc detail in a general-purpose metadata element.

It doesn't show that matching should not be addressed in the same document; it merely shows that one particular algorithm doesn't meet all needs. It would be possible to move all discussion of matching to another document, but I don't see any reason why that must be done. The draft discusses some general considerations and leaves plenty of room for separate specifications for particular matching algorithms for use in particular applications.

I was merely trying to point out that the questions you are asking are not new, that decisions *have* been taken, and that the results are now part of the Internet legacy. You are certainly welcome to consider whether there's a better way and to propose some entirely new infrastructure for the Internet, but that should not prevent those of us who have been working on the evolution of the existing infrastructure for the past several years to continue to move forward in that evolution.
Or were you suggesting that at any time anybody should be able to question whether standards that have been in use for some time were formed with adequate consensus?

RFC 1591 and RFC 1958 are specifications for completely separate protocols. Not only is it completely inappropriate to suggest that RFC 1766 or its successors must be subject to these unrelated specifications, to do so would break a large number of existing implementations of RFC 1766 and RFC 3066 (let alone the proposed revision). This is truly nonsense.

The goals for the proposed revision in enhancing RFC 3066 are clearly stated in the draft.
