Hi Nicolas,

I'm a bit confused by your message.

In the patch there's ox-latex where e.g. KOMA-Script has as
subtitle-macro.  ox-html, ox-ascii, ox-odt all are pretty liberate formats
in terms of what elements are supported.

OK.  ox and org-element shouldn't be touched by the patch.

Yeah, I still have a patch for that...  I still have to do the
documentation changes.

IMO it is.  The only place where there's a "hack" is in ox-latex and
that's cause article is the default class.  If you prefer, it can just
output to the \subtitle{·} by default and say it's KOMA-script only.  That
seems harsh, though.

The patch doesn't touch ox-texinfo.  I don't mind fixing that bug, though.
