Out of curiosity: in what context?

>> 1. Section 5.3 (Zip Relative Paths). The ABNF defines "language-range". I think this is not desirable. Language ranges are input to the matching algorithm (i.e. the user's request). You don't really want paths like "locale/de-*-1901". You want concrete paths here and "*" has no business in a path. Ideally you would reference the "Language-Tag" production in BCP 47 (RFC 5646). However, since it is a large production and you don't probably want to directly incorporate it, you could incorporate the "obs-language-tag" production in the same document instead. You should still say that language tags used in paths "must" be valid language tags according to the more formal production.

+1, it's a bug.

>> 2. Section 5.3. The same production corresponds to BCP 47 (RFC 4647) "extended-language-range", although it only allows the tags to use lowercase letters. I really feel that mixed case is not that difficult to support and that it will save many developers from inexplicable silent failures.

I would very much prefer that we stuck with case-sensitive; I think that developers can handle that trivially.
