Actually, I was wrong! It is only the headers that are in the #+BEGIN_SRC l=
ine that get stripped.  The contents of any #+header: lines are left  alone=
 and the src-block transcoder will have access to them as the :header eleme=
nt of a plist in the src-block argument.=20

r) intact?


I think this might work: Add `after' advice to `org-babel-exp-code' that co=
pies the header args you want to retain and prepends a #+header: line with =
them to the string returned by org-babel-exp-code.  Then your src-block tra=
nscoder can find them.
