+ * through annotation. These definition arrays may be altered through
+ * hook_editor_info_alter(). The definition includes the following keys:
+ *
+ * - id: The unique, system-wide identifier of the text editor. Typically named
+ *   the same as the editor library.
+ * - label: The human-readable name of the text editor, translated.
+ * - supports_content_filtering: Whether the editor supports "allowed content
+ *   only" filtering.
+ * - supports_inline_editing: Whether the editor supports the inline editing
+ *   provided by the Edit module.
+ * - is_xss_safe: Whether this text editor is not vulnerable to XSS attacks.
+ * - supported_element_types: On which form element #types this text editor is
+ *   capable of working.
+ *
+ * A complete sample plugin definition should be defined as in this example:
+ *
+ * @code
+ * @Editor(
