* @Short_description: The ATK interface implemented by components
* containing user-editable text content.
* @Title:AtkEditableText
*
* #AtkEditableText should be implemented by UI components which
* contain text which the user can edit, via the #AtkObject
* corresponding to that component (see #AtkObject).
*
* #AtkEditableText is a subclass of #AtkText, and as such, an object
* which implements #AtkEditableText is by definition an #AtkText
* implementor as well.
*
* See also: #AtkText
