Reciprocal of 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
DESCRIBED_BY. If the detailed information describes an error condition,
ERROR_FOR should be used instead. Since: ATK-2.26.
