No, you didn't miss anything. I was thinking about
`org-special-blocks.el'. The exporter doesn't implement org-exp-blocks
functionalities.

Though, IIRC, org-exp-blocks was mostly deprecated when Babel was
introduced. That's why old ditaa and dot "exp-blocks" were moved to src
block languages.

It is data. Source code is for the processing function.

Anyway, just store your text in example blocks, and create a src block
in any language to do the processing. Then you can call the processing
function on all of your example blocks.

I suggest to keep the example blocks in a non-exportable section. You
can also remove all named example blocks before export, via a hook. Your
call.

#+begin_src org
* Data                                                                  
:noexport:
  
  #+name: words
  #+BEGIN_EXAMPLE
  a b c
  #+END_EXAMPLE
  
  #+name: 
  #+BEGIN_SRC emacs-lisp :var x=words
  (upcase x)
  #+END_SRC

* Contents

  #+call: words(:var x=words)
#+end_src
