 * @start_offset: the text offset of the beginning of the selection within
 *                @start_object.
 * @end_object: the AtspiAccessible containing the end of the selection.
 * @end_offset: the text offset of the end of the selection within @end_object.
 * @start_is_active: a gboolean indicating whether the start of the selection
 *                  is the active point.
 *
 * This structure represents a single  text selection within a document. This
 * selection is defined by two points in the content, where each one is defined
 * by an AtkObject supporting the AtkText interface and a character offset
 * relative to it.
 *
 * The end object must appear after the start object in the accessibility tree,
 * i.e. the end object must be reachable from the start object by navigating
 * forward (next, first child etc).
 *
 * This struct also contains a @start_is_active boolean, to communicate if the
 * start of the selection is the active point or not.
 *
 * The active point corresponds to the user's focus or point of interest. The
 * user moves the active point to expand or collapse the range. The anchor
 * point is the other point of the range and typically remains constant. In
 * most cases, anchor is the start of the range and active is the end. However,
 * when selecting backwards (e.g. pressing shift+left arrow in a text field),
 * the start of the range is the active point, as the user moves this to
 * manipulate the selection.

 * Since: 2.52
