Not as you have it there, but
#+header: :frag (appear appear)
#+begin_r-stack
[[imglink1]]
[[imglink2]]
#+end_r-stack
parses as
(special-block
(:type "r-stack" :begin 727 :end 815 :contents-begin 775 :contents-end 801
:post-blank 0 :post-affiliated 759 :header
(":frag (appear appear)")
:mode nil :granularity element :parent nil))
if that helps.
