This is all perfectly clear: I did restart emacs (several times) after
putting in the setq commands to set those variables.  

However, I guess the instructions you give are actually subtly
incorrect?  That is, from what you say above, using setq is not going
to work because that doesn't invoke any hooks for the particular
variables.  Therefore these variable must (?)  be set through
customize?  Or is there some way to invoke, automatically, the hooks
when setting a variable directly?  Probably not.

FYI, I am happy in principle to use customize but I don't use it in
general because I share my emacs configuration amongst a number of
machines and tend to use customize *only* for those variables that are
different on each system (e.g. only emacs 22 is available on my
internet table).  This makes it easy to have an almost consistent
environment regardless of the system I'm using.

Anyway, thanks again: using @text@ now works very nicely both in org
mode and in the export!
