Aha! I missed that part in the newer manual.

Note that the manual only talks about setting
`org-latex-packages-alist'. Not the keyword.

Maybe we can add the #+LATEX_HEADER example to the manual.

I think that it is a good idea. I do not recall common language
abbreviations to be case-sensitive in other software.

Now, let me continue to act like an ordinary user and follow your
suggestion :)

I tried to add the header:

#+title: Temp
#+LATEX_COMPILER: lualatex
#+LANGUAGE: he
#+LaTeX_Header: \usepackage[AUTO]{polyglossia}

\begin{equation}
f(x) = \frac{8}{7}
\end{equation}

#+begin_src python :exports code
for i in range(3):
	print("hello")
#+end_src

Then, C-c C-e l o

And I get an error...
