The copy buffer that org-export-as sets up will contain this src block *aft=
er* the babel process runs.

#+BEGIN_SRC emacs-lisp -n
(message "This is line 1")
(message "This is line 2")
(message "This is line 3")
(message "This is line 4")
(message "This is line 5")
#+END_SRC


As you can see the headers are stripped off of it.

So you need to do something tricky to hold onto those headers.  I do not kn=
ow of a seamless way to do this.  FWIW, this is handled in ox-ravel by hack=
ing babel so it produces #+ATTR_ lines just before the src block result in =
the copy buffer. Those lines hold the header info which the ravel exporter =
trancoders can consult.

There might be a tricky way to use :wrap to rewrite the src block with the =
other headers intact.

HTH,
