`ATK_RELATION_FLOWS_FROM`

  Indicates that the object has content that flows logically from another AtkObject in a sequential way, (for instance text-flow).

  - Value: `8`
  - Available since: 1.0
`ATK_RELATION_SUBWINDOW_OF`

  Indicates a subwindow attached to a component but otherwise has no connection in the UI heirarchy to that component.

  - Value: `9`
  - Available since: 1.0
`ATK_RELATION_EMBEDS`

  Indicates that the object visually embeds another object’s content, i.e. this object’s content flows around another’s content.

  - Value: `10`
  - Available since: 1.0
`ATK_RELATION_EMBEDDED_BY`

`ATK_RELATION_DESCRIBED_BY`

  Reciprocal of `ATK_RELATION_DESCRIPTION_FOR`. Indicates that one or more target objects provide descriptive information about this object. This relation type is most appropriate for information that is not essential as its presentation may be user-configurable and/or limited to an on-demand mechanism such as an assistive technology command. For brief, essential information such as can be found in a widget’s on-screen label, use `ATK_RELATION_LABELLED_BY`. For an on-screen error message, use `ATK_RELATION_ERROR_MESSAGE`. For lengthy extended descriptive information contained in an on-screen object, consider using `ATK_RELATION_DETAILS` as assistive technologies may provide a means for the user to navigate to objects containing detailed descriptions so that their content can be more closely reviewed.

  - Value: `14`
  - Available since: 1.0
`ATK_RELATION_DESCRIPTION_FOR`

  Reciprocal of `ATK_RELATION_DESCRIBED_BY`. Indicates that this object provides descriptive information about the target object(s). See also `ATK_RELATION_DETAILS_FOR` and `ATK_RELATION_ERROR_FOR`.

  - Value: `15`
  - Available since: 1.0
`ATK_RELATION_NODE_PARENT_OF`

  Indicates an object is a cell in a treetable and is expanded to display other cells in the same column.

  - Value: `16`
  - Available since: 1.0
`ATK_RELATION_DETAILS`

  Reciprocal of `ATK_RELATION_DETAILS_FOR`. Indicates that this object has a detailed or extended description, the contents of which can be found in the target object(s). This relation type is most appropriate for information that is sufficiently lengthy as to make navigation to the container of that information desirable. For less verbose information suitable for announcement only, see `ATK_RELATION_DESCRIBED_BY`. If the detailed information describes an error condition, `ATK_RELATION_ERROR_FOR` should be used instead. `Since`: ATK-2.26.

  - Value: `17`
  - Available since: 1.0
`ATK_RELATION_DETAILS_FOR`

  Reciprocal of `ATK_RELATION_DETAILS`. Indicates that this object provides a detailed or extended description about the target object(s). See also `ATK_RELATION_DESCRIPTION_FOR` and `ATK_RELATION_ERROR_FOR`. `Since`: ATK-2.26.

  - Value: `18`
  - Available since: 1.0
`ATK_RELATION_ERROR_MESSAGE`

  Reciprocal of `ATK_RELATION_ERROR_FOR`. Indicates that this object has one or more errors, the nature of which is described in the contents of the target object(s). Objects that have this relation type should also contain `ATK_STATE_INVALID_ENTRY` in their `AtkStateSet`. `Since`: ATK-2.26.

  - Value: `19`
  - Available since: 1.0
`ATK_RELATION_ERROR_FOR`
