I know of two other wrinkles in the RFC 1766 world:
Are you aware that RFC 1766 has been obsolete for four years now?
(2) SGN- requires special handling, in that SGN-FR and SGN-EN are in fact
sufficiently different languages that a primary tag match should not be
taken to be a generic match.
The same is true of the various registered zh-* tags.
(a) Extension tags appear as the first subtags, and as such have to
be taken into account when looking for country subtags.
Finding country codes is straightforward: any non-initial subtag of two letters
(not appearing to the right of "x-" or "-x-") is a country code.
This is true in RFC 1766, RFC 3066, and the current draft.
(b) Script tags change the complexion of the matching problem significantly,
in that they can interact with external factors like charset information
in odd ways.
Can you clarify this? Charset information neither specifies nor necessarily
restricts (except in text/plain) the script used to write a document.
(c) UN country numbers have been added (IMO for no good reason), requiring
handling similar to country codes.
They provide for supranational language varieties and for stability in
country codes which is inappropriate for ISO 3166 alphabetic codes (which
are codes for country *names*).
The bottom line is that while I know how to write reasonable code to do RFC
1766 matching (and have in fact done so for widely deployed software), I
haven't a clue how to handle this new draft competently in regards to
matching.
The draft describes only the RFC 1766 (3066) algorithm, without excluding
other algorithms to be defined later.
