"Do not install junction boxes in the
attic or conceal them in walls."

That makes no sense at all. That would mean that junction boxes must be
on the surface of the wall (how 'bout that exposed Romex?) and in the
basement, I guess.

There are some other bizarro factoids in that PDF file. Like how the
roughing-in inspection has to be done with all insulation off, what the
heck can that mean?

I'm sure that whoever wrote those sections had good intentions but I
doubt he intended it to be read the way we are.

Tim.
