Framemaker was great, was the tool used by most US military contractors in 90s. Many well known aircraft were designed using this document tool. I still try to configure MS Word to work like it.
Exactly. Interleaf was structured-oriented like that, only a bit moreso. (I designed "styles" heavily in all 3 tools, plus some others.)
Regarding mil/aero, I heard (possibly incorrect) that Boeing did some documentation in Interleaf, and part of routine preservation of those engineering artifacts was to archive... an entire Apollo Domain workstation network. Even though later/other versions of Interleaf were available on later platforms. I guess they weren't going to take any chances.
