1.3.2 File Node Lists
File node lists are the building blocks organizing all of the data in the file. There are multiple file node lists that form a tree hierarchy beginning with the root file node list (section 2.1.14), as shown in the following diagram.
The root file node list enumerates all of the object spaces (section 2.1.4) in the revision store, and the file data store list, if present. It also identifies the root object spaces, as shown in the following diagram.
