terminology question, is "language tag" or "locale id" more common? i see both IsStructurallyValidLanguageTag and CanonicalizeUnicodeLocaleId AOs

https://tc39.es/ecma402/#sec-language-tags

This specification identifies locales using Unicode BCP 47 locale identifiers as defined by Unicode Technical Standard #35 Part 1 Core, Section 3.3 BCP 47 Conformance, and its algorithms refer to Unicode locale nonterminals defined in the grammars of Section 3 Unicode Language and Locale Identifiers. Each such identifier can also be referred to as a language tag, and is in fact a valid language tag as that term is used in BCP 47.

"locale identifier" is more formal
