The copy buffer that org-export-as sets up will contain this src block *after* the babel process runs.

As you can see the headers are stripped off of it.

Oh! That explains!
So you need to do something tricky to hold onto those headers.  I do not know of a seamless way to do this.  FWIW, this is handled in ox-ravel by hacking babel so it produces #+ATTR_ lines just before the src block result in the copy buffer. Those lines hold the header info which the ravel exporter trancoders can consult.

I like that approach. I found your ox-ravel project on GitHub and have tangled it to ox-ravel.el.

It would be great if you an paste the revelant snippets of code here as that library is ~800 lines.

I still hope there is some way to prevent doing this hack, or if a non-intrusive change in Org code can still have the :parameters available during export. Would it be possible to remove *only* babel-recognized parameters and leave the unidentified parameters (which could be specific to an exporter) intact?
