I agree with Robert and the analogy with maths notation only reinforces that:
when I was a student of maths, I frequently cursed the authors of
papers I was reading for using notation without definition.  Of
course, it was perfectly clear to someone seasoned in the area of the
paper, because the notation was conventional - but a puzzle for a
newbie.
