8.2.1 Intl.getCanonicalLocales (locales)
|
|
1. Let ll be ? CanonicalizeLocaleList(locales).
|
|
2. Return CreateArrayFromList(ll).

7. Repeat, while k < len

c. If kPresent is true, then
|
|
...
|
|
v. If IsStructurallyValidLanguageTag(tag) is false, throw a RangeError exception.
|
|
vi. Let canonicalizedTag be CanonicalizeUnicodeLocaleId(tag).

UTS 35, §3.2.1 Canonical Unicode Locale Identifiers
|
|
Use the bcp47 data to replace keys, types, tfields, and tvalues by their canonical forms.
|

See Section 3.6.4 U Extension Data Files) and Section 3.7.1 T Extension Data Files. The
|
|
aliases are in the alias attribute value, while the canonical is in the name attribute value.
