A `footnote-reference' is an object type (see
`org-element-all-objects'), not an element: as such it doesn't belong to
`org-element-all-elements'.
`org-element-secondary-value-alist' is a list of elements and objects
containing a secondary string.

Ok, I see, thanks.
What about
,----------------
| latex-or-entity
| plain-link
| text-markup
`----------------
in
,---------------------------------------------------------------------------------
| (defconst org-element-all-successors
| '(export-snippet footnote-reference inline-babel-call inline-src-block
| latex-or-entity line-break link macro plain-link radio-target
| statistics-cookie sub/superscript table-cell target
| text-markup timestamp)
| "Complete list of successors.")
`---------------------------------------------------------------------------------
?
They seem to be neither elements nor objects - are they a kind of
'abstract categories' for some object types?
And I must admit that I'm not sure about the exact meaning of
'successors'. You describe elements and objects in detail in the
comment-section of org-element.el, but don't mention 'successors'.
,---------------------------------------------------------------------
| (defconst org-element-object-successor-alist
| '((subscript . sub/superscript) (superscript . sub/superscript)
| (bold . text-markup) (code . text-markup) (italic . text-markup)
| (strike-through . text-markup) (underline . text-markup)
| (verbatim . text-markup) (entity . latex-or-entity)
| (latex-fragment . latex-or-entity))
| "Alist of translations between object type and successor name.
| Sharing the same successor comes handy when, for example, the
| regexp matching one object can also match the other object.")
`---------------------------------------------------------------------
The relation between object/successor is like concrete
subclass(es)/abstract superclass?
PS
I hope I don't go on your nerves with my questions, but I'm trying to
understand how you modeled an Org-file and its not all clear to me.

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.
