    //   automatic  the filter is configured by editor features (like plugins, buttons, and commands) that are enabled with configuration options
    //               such as CKEDITOR.config.plugins, CKEDITOR.config.extraPlugins, and CKEDITOR.config.toolbar,
    //   custom     the filter is configured by the CKEDITOR.config.allowedContent option and only features that match this setting are activated.
    // In both modes it is possible to extend the filter configuration by using the CKEDITOR.config.extraAllowedContent setting.
    // If you want to disable Advanced Content Filter, set CKEDITOR.config.allowedContent to true. All available editor features will be activated and input data will not be filtered.
    // Allowed content rules. This setting is used when instantiating CKEDITOR.editor.filter.
    // The following values are accepted:
    //     CKEDITOR.filter.allowedContentRules  defined rules will be added to the CKEDITOR.editor.filter.
    //     true  will disable the filter (data will not be filtered, all features will be activated).
    //     default  the filter will be configured by loaded features (toolbar items, commands, etc.).
