In my testing, in order to make Emacs ignore the `foo: bar' binding, the
empty Local Variables list actually needs to go first.

Yes, I agree that Org should not deal with this feature.

Splitting the example into two parts results in "File mode specification
error: (user-error Local variables entry is missing the prefix) " upon
opening the file.  You can test with this:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC org
  # Local Variables:
#+END_SRC

#+BEGIN_SRC org
  # org-srs-review-new-items-per-day: 30
  # org-srs-review-max-reviews-per-day: 100
  # End:
#+END_SRC
--8<---------------cut here---------------end--------------->8---

By the way, is there a built-in command to copy that (info ...) sexp
when viewing that info page?

Thanks, I just re-read that page more carefully, and I see this:

    If some unrelated text might look to Emacs as a local variables
    list, you can countermand that by inserting a form-feed character (a
    page delimiter, *note Pages::) after that text.  Emacs only looks for
    file-local variables in the last page of a file, after the last page
    delimiter.

In the org-srs README.org, I think we can just throw a \f at the bottom
of the file (or before a Local Variables list which we do want to use).

Problem solved!  Thank you, Max!
