[O] About the use of PROPERTY "meta lines"...

[Sebastien Vauban]

#+TITLE:     Properties
#+AUTHOR:    Seb Vauban

#+PROPERTY: var  foo=1
#+PROPERTY: var+ bar=2

* Abstract

IIUC, properties are set in this way:

- on a file basis, before any heading, through the =PROPERTY= keyword,
- on a subtree basis, through the =PROPERTIES= block.

My comprehension is that the =PROPERTY= keyword may not be used inside "trees",
and should be ignored if that would happen.

The following example shows that either:

- I'm wrong to think so,
- there is a bug.

What is the right assumption here?

* Subtree

Being located in a subtree, the following lines are ill-placed IMHO:

#+PROPERTY: var  foo="Hello
#+PROPERTY: var+ world"

Though, they're well taken into account:

#+begin_src emacs-lisp
  foo
#+end_src

#+results:
: Hello world

These lines have even wiped the definition of =bar= (because of the use of =var=
without any =+=):

#+begin_src emacs-lisp
  (+ foo bar)
#+end_src

returns the error "Symbol's value as variable is void: bar."

Best regards,
  Seb
