 * The SiLocaleId is used to provide a locale id from the translate service
 * to the angular localization. The Angular services call toString or valueOf
 * so that the current locale of the translation service is provided. The Intl.
 * library does not invoke toString() and using the value directly in Intl
 * formatting results always having the `en` locale. Thus, when using the SiLocaleId
 * in other services, make sure to use the `toString()` method before.
