As I explained, both are linked:

  - Anything defined in "ox.el" is documented in "Export settings" ;
  - Anything defined in "ox-backend.el" is documented in "Backend
    export".

This is a hard rule. Even if it means repeating documentation in three
different places, some back-end might use differently the same keyword
than others.

For the record, if the situation ever rises again, I think that
a keyword can be added to "ox.el" only if

  - it is supported at least in every major back-end (ASCII, HTML,
    LaTeX, ODT and Texinfo)
  - it comes with a toggle in the OPTIONS line e.g. keyword:nil

Even when these criteria are met, this move shouldn't be taken lightly
as it implies all back-ends should try hard to support it.

Again, keywords in this category are to be documented in 

  (info "(org)Export settings").

SUBTITLE, DESCRIPTION and KEYWORDS can be defined in the libraries where
they are used. Only the documentation needs to be adapted, per above.

Sorry for the confusion.

Forget about it. I'm not sure DESCRIPTION should be handled at all in
ASCII back-end.
