| Test Unicode extension subtag canonicalisation for the "rg" extension key. |
| 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. 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. |
| |
| Replace aliases in special key values: |
| If there is an 'sd' or 'rg' key, replace any subdivision alias in its value in the same way, |
| using subdivisionAlias data. |
