To be more precise, I want to emulate
#+LATEX_HEADER: \makeatletter
#+LATEX_HEADER+: \@setplength{refvpos}{\useplength{toaddrvpos}}
#+LATEX_HEADER+: \makeatother

(as a full file export, which yields 3 separate lines), for a subtree
export, were the property :EXPORT_LATEX_HEADER: is used.

Best,

Alan
