Yes, indeed.  I'd forgotten this distinction, which Erik Iverson spelled
out clearly several years ago:
http://article.gmane.org/gmane.emacs.orgmode/26082

Unless Erik minds, I'll work his post into ob-doc-R when I find some
time.  IMO, it would be nice to have this kind of systematic description
in the first place one goes for help.

Thanks, this code will be useful as I pick up this project, which was
the first time I tried to do something substantial with Org mode.  I'm
going to find a ton of cruft ...

All the best,
Tom
