I hadn't heard this before, and was curious (especially since the paper being discussed is from 1996, 25 years ago) so I did a quick Google to see what was out there. This paper [0] describes how Goldberg first mentioned the idea on the PsyCom BBS (which he founded) in 1995, apparently as a response to his issues with the DSM IV, which had just been published the year before.
So, I learned that today - thanks, 'bigger_inside ;)
