Hi,
in Worg's description of Org's syntax, there is a section about "greater
blocks" [1]. The syntax is
#+begin_NAME PARAMETERS
CONTENTS
#+end_NAME
There is then a "PARAMETERS" optional string attached to special
blocks. Unfortunately, in the special-block transcoder I'm writing, I
have no clue how to access the parameters. I can't find any parameters
function in org that would be related.
What is the best way to access the parameters of a special-block?

My understanding is that the parameters line is just ignored for special blocks. I wrote and used a patch a while ago to fix this; it was on my todo list to clean it up and submit it to org. Now looks like a good time. My patch adds a `:parameters-line' property to org elements that are special blocks, storing the PARAMETERS line as a string. See attached patch. Could this be added to org ?
