Interesting. That sounds like a different commercial strain, "SoftQuad
was started in order to improve automated typesetting at Toronto's
Coach House Press, and for many years developed an enhanced commercial
version of the text formatting program troff, developed under license
from AT&T, called sqtroff. It was sold with a suite of associated
programs, corresponding to AT&T's Documenter's Workbench, under the
name SoftQuad Publishing Software (SQPS)."

From there things get a little less clear, it seems like we jump to
3.2 with SysVR3.2?
The jump might be due to the effect that for quite a while outside
AT&T it was marketed by SoftQuad (Toronto). (See also
