Hehe. Simple as that.

I thought this might get replaced on babel block execution. I was
wrong.

I now have two working solutions:


****** Solution 1: https://orgmode.org/manual/post.html#post

#+name: attr_wrap
#+begin_src sh :var data="" :var width="\\textwidth" :results output
  echo "#+ATTR_LATEX: :width $width"
  echo "$data"
#+end_src

#+BEGIN_SRC plantuml :post attr_wrap(width="1cm", data=*this*) :results drawer 
:file (make-temp-file "export-example-1-" nil ".png")
(*) --> "step1"
--> "step2"
--> (*)
#+END_SRC

#+RESULTS:
:RESULTS:
#+ATTR_LATEX: :width 1cm

:END:

****** Solution 2: "put the desired #+attr_latex: line just before the 
#+results line."

#+BEGIN_SRC plantuml :file (make-temp-file "export-example-2-" nil ".png")
(*) --> "step1"
--> "step2"
--> (*)
#+END_SRC

#+ATTR_LATEX: :width 2cm
#+RESULTS:
[[file:c:/Users/KARL~1.VOI/AppData/Local/Temp/export-example-2-nvoWbD.svg]]
