Thinking of the kinds of documents: consider that, well into the 1980s and 
1990s, sending out letters to mailing lists was a common scenario, and 
that requires the ability to handle both text (the letter form) and 
database (the address list) functions, and merge the two.

That’s “document production”, but it probably doesn’t count as “technical 
document production” (manuals, teaching material etc).
