The Organizes ReferenceType can be used by Objects (of type FolderType) and Views (see 7.11).

However, in 5.23 it is stated that this ReferenceType should only be used by Objects of type FolderType.

Suggested changes of the text:

New Text:
The ObjectType FolderType is formally defined in Part 5. Its purpose is to provide Objects that have no other semantic than organizing of the AddressSpace. A special ReferenceType is used for those Folder Objects, the Organizes ReferenceType. The SourceNode of such a Reference should always be a View or an Object of the ObjectType FolderType; the TargetNode can be of any NodeClass. Organizes References can be used in any combination with HasChild References (HasComponent, HasProperty, etc.; see 7.5) and do not prevent loops. Thus, they can be used to span multiple hierarchies.
