No: I used to edit and compile my `.dtx` files this way.

OK. Because I don't understand all the mysteries of Emacs/AUCTeX,
I hadn't the impression to load two major modes since I hadn't:

  ┌────
  │ %%% mode: tex
  │ %%% mode: doctex
  └────

Indeed, replacing:

  ┌────
  │ %%% mode: tex
  │ %%% eval: (doctex-mode)
  └────

by :

  ┌────
  │ %%% mode: doctex
  └────

did the trick.

I remember spending a lot of time researching how to both, and without
error, edit with `doctex` mode and compile with `pdftex`; but I can't
remember why the only solution that worked at the time of my research
was this one, which was obviously flawed.

Thanks!
