Nothing really wrong on your side. It is probably an omission on the Org
side.

Executing the above code produces

#+RESULTS: html transformation
[[file:img/transformation-html.svg]]

However, it is currently impossible to link to such results paragraph by
itself - only to the parent src block. Since you are using :exports
results, the export code does not "see" the src block; only the results
block which cannot be referenced. Hence, the error.

They way to work around the problem is providing explicit name anchor to
the results block:

------------
#+name: html transformation
#+begin_src plantuml :file img/transformation-html.svg :exports results :mkdirp yes
   file org
   file html
   org -> html : org-html-publish-to-html
#+end_src

#+name: html transformation result
#+RESULTS: html transformation
[[file:img/transformation-html.svg]]

Now I want to include an internal link to this figure with [[html
transformation result]]. This works now.
------------

Though I do agree that the current behaviour is not intuitive in this
specific scenario. When a user provides :exports results, it would make
sense to inherit all the affiliated keywords, including #+name and
possibly various #+attr_* to the results of evaluation.

On the other hand, inheriting may be tricky. I can imagine situations
when such inheritance is not desired and a user actually prefers to
state the results keywords manually.

I am not sure what would be the best way to handle the situation at hand
while not breaking the other :exports variants.

Best,
Ihor
