     * Code Actions can also be attached to info, warning, and error messages as Quick Fixes.
     * Constructors in type `LanguageService` are renamed to align them with the corresponding requests in LSP. Usage of the old names is now deprecated.
     * Keyword parameter `useSpecialCaseHighlighting` is introduced on constructor `parsing` of type `LanguageService` (default: `true`). It is used to control whether or not the semantic highlighter should apply an odd special case (i.e., categories of `syntax` non-terminals are sometimes ignored); the semantic highlighter has been applying this special case for several releases. Usage of the special case is now deprecated.
