I do, in the "Objects" section. Successors are functions used to find
the next object of a given type. Some objects are so close that they can
share the same successor. Hence `text-markup' is a successor shared by
underline, code, verbatim, bold, italic and strike-through objects. See
`org-element-object-successor-alist' for more information.

Also, see comments above `org-element--parse-elements' to get
information about the algorithm used for object research.

There are comments at the beginning of each section in the file: these
should give you some answers. Don't hesitate to ask if they don't
fulfill your needs.
