If it does not take you too much time, can you enlighten me on the diffs
between the chunks?  Why was it well working for the second one?

References are working well. Thanks a lot!

Though, there is an annoying diff in the tangled LaTeX: the first block gets
an extra blank line (I don't understand why it differs from the others) which
will cause layout problem when compiling the document -- not this one, it's
just an not-so-valid ECM, but real ones...

#+begin_src latex
  \documentclass{article}
  \usepackage[utf8x]{inputenc}
  \usepackage[T1]{fontenc}

  \begin{document}

  \begin{textblock}{85}(98,35)
  \titlebox{9.4cm}{Foo}{% HERE 1111 <<<<
  1111ToMe

  }
  \end{textblock}

  \begin{textblock}{110}(25,195)
      Some sentence
      2222BeforeDate
       \hfill{}% HERE 2222 <<<<
      3333Rest
       EUR% HERE 3333 <<<<
  \end{textblock}

  \end{document}
#+end_src

Best regards,
  Seb
