How not to remove other back-ends specific contents using org-org-export-to-org?

Question

Using org-org-export-to-org:

#+ATTR_HTML: :style max-width:60%;
[[file:data/fool_f7dc.png]]

Is exported as:

[[file:data/fool_f7dc.png]]

Is there a way to keep the line #+ATTR_HTML: :style max-width:60%;?

Thx!

Edit:

Tried suggestion solution:

#+begin_export org
#+ATTR_HTML: :style max-width:60%;
[[file:data/fool_f7dc.png]]
#+end_export

But does not work since org-org-export-to-org returns:

#+BEGIN_export
[[file:data/fool_f7dc.png]]
#+END_export

Answer 1

An export block would be an option:

#+begin_export org
#+ATTR_HTML: :style max-width:60%;
[[file:data/fool_f7dc.png]]
#+end_export
