  *@ATK_ROLE_CHART: The object is a graphical depiction of quantitative data. It may contain multiple subelements whose attributes and/or description may be queried to obtain both the quantitative data and information about how the data is being presented.

  * always have ATK_ROLE_FORM. (Since: 1.12.0)
  *@ATK_ROLE_LINK: The object is a hypertext anchor, i.e. a "link" in a
  * hypertext document.  Such objects are distinct from 'inline'
  * content which may also use the Hypertext/Hyperlink interfaces
  * to indicate the range/location within a text object where
  * an inline or embedded object lies.  (Since: 1.12.1)
  *@ATK_ROLE_INPUT_METHOD_WINDOW: The object is a window or similar viewport
  * which is used to allow composition or input of a 'complex character',
  * in other words it is an "input method window." (Since: 1.12.1)
  *@ATK_ROLE_TABLE_ROW: A row in a table.  (Since: 2.1.0)

  *@ATK_ROLE_LIST_BOX: A non-collapsible list of choices the user can select from. (Since: 2.1.0)
  *@ATK_ROLE_GROUPING: A group of related widgets. This group typically has a label. (Since: 2.1.0)
  *@ATK_ROLE_IMAGE_MAP: An image map object. Usually a graphic with multiple hotspots, where each hotspot can be activated resulting in the loading of another document or section of a document. (Since: 2.1.0)
  *@ATK_ROLE_NOTIFICATION: A transitory object designed to present a message to the user, typically at the desktop level rather than inside a particular application.  (Since: 2.1.0)
  *@ATK_ROLE_INFO_BAR: An object designed to present a message to the user within an existing window. (Since: 2.1.0)

  * composition that forms an independent part of a document, page, or
  * site. Examples: A blog entry, a news story, a forum post. (Since: 2.12)
  *@ATK_ROLE_LANDMARK: A region of a web page intended as a
  * navigational landmark. This is designed to allow Assistive
  * Technologies to provide quick navigation among key regions within a
  * document. (Since: 2.12)
  *@ATK_ROLE_LOG: A text widget or container holding log content, such
  * as chat history and error logs. In this role there is a
  * relationship between the arrival of new items in the log and the
  * reading order. The log contains a meaningful sequence and new
  * information is added only to the end of the log, not at arbitrary
  * points. (Since: 2.12)
  *@ATK_ROLE_MARQUEE: A container where non-essential information
  * changes frequently. Common usages of marquee include stock tickers
  * and ad banners. The primary difference between a marquee and a log
  * is that logs usually have a meaningful order or sequence of
  * important content changes. (Since: 2.12)
  *@ATK_ROLE_MATH: A text widget or container that holds a mathematical
  * expression. (Since: 2.12)
  *@ATK_ROLE_RATING: A widget whose purpose is to display a rating,
  * such as the number of stars associated with a song in a media
  * player. Objects of this role should also implement
  * AtkValue. (Since: 2.12)
  *@ATK_ROLE_TIMER: An object containing a numerical counter which
  * indicates an amount of elapsed time from a start point, or the time
  * remaining until an end point. (Since: 2.12)
  *@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: 2.12)
  *@ATK_ROLE_DESCRIPTION_TERM: An object that represents a term or phrase
  * with a corresponding definition. (Since: 2.12)
  *@ATK_ROLE_DESCRIPTION_VALUE: An object that represents the
  * description, definition or value of a term. (Since: 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: 2.16)
  *@ATK_ROLE_MATH_FRACTION: An object that represents a mathematical fraction.
  * (Since: 2.16)
  *@ATK_ROLE_MATH_ROOT: An object that represents a mathematical expression
  * displayed with a radical. (Since: 2.16)
  *@ATK_ROLE_SUBSCRIPT: An object that contains text that is displayed as a
  * subscript. (Since: 2.16)
  *@ATK_ROLE_SUPERSCRIPT: An object that contains text that is displayed as a
  * superscript. (Since: 2.16)
  *@ATK_ROLE_FOOTNOTE: An object that contains the text of a footnote. (Since: 2.26)
  *@ATK_ROLE_CONTENT_DELETION: Content previously deleted or proposed to be
  * deleted, e.g. in revision history or a content view providing suggestions
  * from reviewers. (Since: 2.34)
  *@ATK_ROLE_CONTENT_INSERTION: Content previously inserted or proposed to be
  * inserted, e.g. in revision history or a content view providing suggestions
  * from reviewers. (Since: 2.34)
  *@ATK_ROLE_MARK: A run of content that is marked or highlighted, such as for
  * reference purposes, or to call it out as having a special purpose. If the
  * marked content has an associated section in the document elaborating on the
  * reason for the mark, then %ATK_RELATION_DETAILS should be used on the mark
  * to point to that associated section. In addition, the reciprocal relation
  * %ATK_RELATION_DETAILS_FOR should be used on the associated content section
  * to point back to the mark. (Since: 2.36)
  *@ATK_ROLE_SUGGESTION: A container for content that is called out as a proposed
  * change from the current version of the document, such as by a reviewer of the
  * content. This role should include either %ATK_ROLE_CONTENT_DELETION and/or
  * %ATK_ROLE_CONTENT_INSERTION children, in any order, to indicate what the
  * actual change is. (Since: 2.36)
  *@ATK_ROLE_PUSH_BUTTON_MENU: A specialized push button to open a menu.
  * (Since: 2.46)
  *@ATK_ROLE_LAST_DEFINED: not a valid role, used for finding end of the enumeration
  *
  * Describes the role of an object
  *
  * These are the built-in enumerated roles that UI components can have
  * in ATK.  Other roles may be added at runtime, so an AtkRole >=
  * %ATK_ROLE_LAST_DEFINED is not necessarily an error.
