I meant these strings that I find in parse-trees that apparently do have a
parent-proptery:

#+begin_src emacs-lisp
(headline ... :title (#("topic number one" 0 16 (:parent #1))))

(paragraph (:begin 114 ...)
#("Hello subtopic number one " 0 26 (:parent #4)))
#+end_src

I concluded that they are the secondary values listed here:

#+begin_quote
org-element-secondary-value-alist is a variable defined in `org-element.el'.
Its value is

((headline . :title)
 (inlinetask . :title)
 (item . :tag)
 (footnote-reference . :inline-definition))

Alist between element types and location of secondary value.
#+end_quote

plus the actual (string) content of paragraphs (e.g.).

I can change the :parent attribute of the headline containing the above
:title string (or of the paragraph containing the above content string)
with `org-element-map', but those :parent references inside the strings
remain untouched.

I can access them by writing some code, of course, I only wanted to know if
`org-element-map' might be able to access them out-of-the-box somehow.
