Alright I'll take another look at this paragraph and see if I can
untangle the verbiage.

actually this should already be implemented, you can specify another
file by constructing your reference as file-name:resource-name, e.g.

with the following saved to ~/Desktop/location.org

  #+source: year
  #+begin_src emacs-lisp
    2010
  #+end_src

  #+source: city
  #+begin_src emacs-lisp
    "Santa Fe"
  #+end_src

the following code block should resolve its references correctly from
*any* buffer

  #+headers: :var city=~/Desktop/location.org:city
  #+headers: :var year=~/Desktop/location.org:year
  #+begin_src emacs-lisp
    (message "I'm in %s in the year %d" city year)
  #+end_src

although apparently there is still some work to be done on this code as
for me it leaves the referenced file open.  This is code that apparently
hasn't been used or documented so I'm sure there will be some kinks to
work out

Yes, thanks for the explanation, this is the first I've heard of this
package but it certainly does seem useful.

Maybe this would be possible to implement using custom links?
