<BR>Hi!<BR>A generic prefix field is very broad indeed and cannot be narrowed later!<BR>But I am not particularly tied to one or the other solution as far as generic and specific prefixes go;<BR>
however, there is no way I would consider registering all possible specific prefixes at once for [alalc97]--just those requested. <BR>Also, I am sort of in favor of deprecating [heploc] for the logic of things<BR>(though it seems a shame to register a subtag and then deprecate it; it's not a good precedent to set normally I don't think)!<BR>

And it perhaps solves the problem of deprecation in a case where the romanization scheme is modified before a particular prefix is requested.<BR>>> <BR>>> It would be easy enough to specify the range of use for alalc97 now.<BR>

It provides a mapping to a Preferred-Value.<BR>Somewhat agreed here though it's only been seven weeks. But it would make sense to register alalc97 for both Russian and Japanese I guess--that would insert some logic and consistency and unity in the variant subtag list.<BR>> <BR>>> > Similarly, if a new set of ALA-LC romanization tables is released,<BR>>> but it differs only in its<BR>>> > treatment of a few languages, would we then have identical text<BR>>> that can be marked equally well as ru-Latn-alalc97 or ru-Latn-<BR>>> ala09 ?<BR>>> <BR>>> Then alalc09 is only registered for use with the changed (or new)<BR>>> languages.<BR>
> Note that, assuming 'alalc97' is not a generic variant and has Prefix fields in its record, wholesale removal of Prefixes is not permitted (RFC 5646, Section 3.1.8), nor is there a mechanism for deprecating only certain uses of a subtag. However, a comment field could be inserted guiding users towards 'alalcXX'. If 'alalc97' is generic, then a new subtag could have prefixes or could also be generic with a note to provide guidance on usage.<BR>This is a problem. I still like the idea of registering this subtag with the list of possible prefixes (two at this moment; Russian and Japanese); at least more prefixes can be added later; if we make this a generic prefix, it gives everyone the use of this subtag without further ado of course--if that is needed. <BR>But this is a much more specific case than fonipa and fonupa and it seems strange having both generic.<BR>

<BR>Hmm. Of course, it would be nice to remove the possibilities for error as much as a list of subtags can.<BR>
