When I start using :var+ or :header-args+, it mostly does not work for me.
What is the syntax for this? Why and how is this used?

* Test
** Works 1
   :PROPERTIES:
   :header-args: :var x=3
   :header-args+: :var y=4
   :END:

#+begin_src emacs-lisp
 (+ x y)
#+end_src

#+results:
: 7

(but does not work when variables reference other src_blocks, see my
bug report about :header-args:)

** Works 2

#+begin_src emacs-lisp :var u=2 v=3
 (+ u v)
#+end_src

#+results:
: 5

** Works 3

#+header: :var u=2
#+header: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

#+results:
: 5

#+headers: :var u=2
#+headers: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

#+results:
: 5

** Does not work

#+header-args: :var u=2
#+header-args+: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+header-args: :var u=2
#+header-args+: :var+ v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+var: u=2
#+var+: v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+var: u=2 v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u


#+begin_src emacs-lisp :var u=2 :var+ v=3
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: v
