         * The available {@link module:language/textpartlanguage~TextPartLanguage}
         * options that allow setting the language of parts of the content.
         *
         * This configuration option is available only with the {@glink api/language text part language feature} enabled.
         *
         * Refer to the [WCAG 3.1.2 Language of Parts](https://www.w3.org/TR/UNDERSTANDING-WCAG20/meaning-other-lang-id.html) specification
         * to learn more.
         *
         * To change the editor's UI language, refer to the {@glink getting-started/setup/ui-language Setting the UI language} guide.
         *
         * The default value is:
         *
         * ```ts
         * const config = [
         * 	{ title: 'Arabic', languageCode: 'ar' },
         * 	{ title: 'French', languageCode: 'fr' },
         * 	{ title: 'Spanish', languageCode: 'es' }
         * ];
         * ```
         *
         * The `title` property will be used by the text part language dropdown to render available options.
         *
         * The `languageCode` property is used for the `lang` attribute in the [ISO 639-1](https://en.wikipedia.org/wiki/ISO_639-1) format.
         *
         * You can also specify the optional `textDirection` property indicating the reading direction of the language.
         * Correct values are `ltr` and `rtl`. When the `textDirection` property is missing, the text part language feature will
         * specify the text direction by itself.
