| Implementations are allowed to canonicalize extension subtag sequences. |
| info: | |
| 8.2.1 Intl.getCanonicalLocales (locales) |
| 1. Let ll be ? CanonicalizeLocaleList(locales). |
| 2. Return CreateArrayFromList(ll). |
| |
| 9.2.1 CanonicalizeLocaleList (locales) |
| ... |
| 7. Repeat, while k < len |
| ... |
| c. If kPresent is true, then |
| ... |
| v. Let canonicalizedTag be CanonicalizeLanguageTag(tag). |
| ... |
| |
| 6.2.3 CanonicalizeLanguageTag (locale) |
| The specifications for extensions to BCP 47 language tags, such as |
| RFC 6067, may include canonicalization rules for the extension subtag |
| sequences they define that go beyond the canonicalization rules of |
| RFC 5646 section 4.5. Implementations are allowed, but not required, |
| to apply these additional rules. |
