Thanks but the following file does not work neither
that is running  org-babel-tangle gives me

Tangled 0 code blocks from tangle2.org
**** tangling with yes or link comments
:PROPERTIES:
:header-args: :comments org
:END:


The top block
#+begin_src emacs-lisp :comments org
  (message "first block")
#+end_src

here's some text which won't be tangled

***** subheading
another block
| 1 | first  |
| 2 | second |
#+source: tangle-el-the-second
#+begin_src emacs-lisp
  (message "second")
#+end_src

and finally a block with a =:noweb= header argument
#+begin_src emacs-lisp :noweb yes
  (progn
    <<tangle-el-the-second>>)
#+end_src
