Hi again,

I can quickly think of two advantages of the late lamented (if only by 
me) #+BABEL header over using properties.

1. Allowing you to specify multiple buffer-wide options on the same 
line (keeping things short), in the same colon :syntax as used in a 
src block header (keeping things consistent and easy to copy back and 
forth). None of this makes a substantive difference.

2. Allowing you to pass multiple buffer-wide arguments with :var. This 
could make a substantive difference in some applications. The 
following will work:

   #+BABEL: :var euro=1.3791 :var salestax=.15

The following will not, since it tries to set the same property:

   #+PROPERTY: var euro=1.3791
   #+PROPERTY: var salestax=.15

If BABEL is dropped for PROPERTY, it would be good for the :var: 
property to support multiple arguments (comma-separated would be good 
for consistency with passing arguments through the SRCNAME). E.g.:

   #+PROPERTY: var euro=1.3791, salestax=.15

I think I'd like this better in any case.

Yours,
Christian
