Probably I'm just slower :)

Yep.  That was why I asked if it was possible to add it on backend basis.
But the oe-parse-secondary-string is fin.  Now I know.

I /think/ that is what I would like.  But I don't understand the what you
mean concretely: would you have something like:

     (:subject "SUBJECT" nil nil space parsed)

I don't understand how it could replace the behavior parameter.  Would it
be a cons?

I agree this is a difficult problem.  Personally, I think it is fine to
consider a keyword as a keyword and nothing more, and not consider content
within a keyword.  However, as I recall, John had a post a while back
about mapping over bold in CAPTIONS or something like that.

I think it may be a mess to interpret content of a keyword at
org-element-map level.  Consider if #+SUBJECT is interpreted with in
ox-koma-letter but not in an imaginary ox-new-letter.  Would it not be
confusing?
