+    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.
