With the following example:

   #+header: :foo bar
   #+begin_export latex
   Foo
   #+end_export

(org-element-property :header (org-element-at-point)) =3D> (":foo bar")

and

(cl-mapcan #'org-babel-parse-header-arguments
           (org-element-property :header (org-element-at-point)))

=3D>

((:foo . "bar"))

True, but this is also true for "attr_...".
