+ *@ATK_ROLE_DESCRIPTION_LIST: An object that represents a list of
+ * term-value groups. A term-value group represents a individual
+ * description and consist of one or more names
+ * (ATK_ROLE_DESCRIPTION_TERM) followed by one or more values
+ * (ATK_ROLE_DESCRIPTION_VALUE). For each list, there should not be
+ * more than one group with the same term name. @Since: ATK-2.12
+ *@ATK_ROLE_DESCRIPTION_TERM: An object that represents the term, or
+ * name, part of a term-description group in a description
+ * list. @Since: ATK-2.12
+ *@ATK_ROLE_DESCRIPTION_VALUE: An object that represents the
+ * description, definition or value of a term-description group in a
+ * description list. The values within a group are alternatives,
+ * meaning that you can have several ATK_ROLE_DESCRIPTION_VALUE for a
+ * given ATK_ROLE_DESCRIPTION_TERM. @Since: ATK-2.12
+ *@ATK_ROLE_STATIC: A generic non-container object whose purpose is to display a
+ * brief amount of information to the user and whose role is known by the
+ * implementor but lacks semantic value for the user. Examples in which
+ * ATK_ROLE_STATIC is appropriate include the message displayed in a message box
+ * and an image used as an alternative means to display text. ATK_ROLE_STATIC
+ * should not be applied to widgets which are traditionally interactive, objects
+ * which display a significant amount of content, or any object which has an
+ * accessible relation pointing to another object. Implementors should expose the
+ * displayed information through the accessible name of the object. If doing so seems
+ * inappropriate, it may indicate that a different role should be used. For
+ * labels which describe another widget, see ATK_ROLE_LABEL. For text views, see
+ * ATK_ROLE_TEXT. For generic containers, see ATK_ROLE_PANEL. For objects whose
+ * role is not known by the implementor, see ATK_ROLE_UNKNOWN. @Since: ATK-2.16.
+ *@ATK_ROLE_MATH_FRACTION: An object that represents a mathematical fraction.
+ * @Since: ATK-2.16.
+ *@ATK_ROLE_MATH_ROOT: An object that represents a mathematical expression
+ * displayed with a radical. @Since: ATK-2.16.
+ *@ATK_ROLE_SUBSCRIPT: An object that contains text that is displayed as a
+ * subscript. @Since: ATK-2.16.
+ *@ATK_ROLE_SUPERSCRIPT: An object that contains text that is displayed as a
+ * superscript. @Since: ATK-2.16.
