Ada 9x (which ultimately became Ada 95) was also a big-money project. But 
all work since has been accomplished basically by volunteers; I'm the only 
paid person, and only for about 1/4 time. (Volunteers don't do the 
paper-pushing jobs that are necessary to finish a project, especially in the 
world of international standards, thus some paid person is necessary, 
certainly for projects that are long-lasting like Ada.)

There was some formalization work for Ada as part of the Ada 9x project 
(remember, "big money" as you described it). I don't know much about it 
other than that it existed; perhaps Tucker Taft or Bob Duff (both of whom 
worked at the center of the Ada 9x project) know more.
