Thanks a lot for the suggestion, here is what I ended up doing:

#+begin_src emacs-lisp
  (defun as/delete-ignored-heading (backend)
    "Remove every headline with a tag `ignoreheading' in the
  current buffer. BACKEND is the export back-end being used, as
  a symbol."
    (org-map-entries
     (lambda () 
       (when (member "ignoreheading" (org-get-tags-at nil t))
         (lambda () (delete-region (point) (progn (forward-line) (point))))))))

  (setq org-export-before-parsing-hook '(as/delete-ignored-heading))
#+end_src

It works great.

I have a followup question (purely from an aesthetic point of view, the
code works fine). I see that a label is still generated in the LaTeX
file (there is a "\label{sec-1}" with just the "\maketitle" above it).
Is it expected?

Thanks again,

Alan
