Thanks. This clarifies things somewhat.

So | and || are "operators". Left a little vague is the "one or more"
part because only some combination are legal. < doesn't combine with >
to make >< even though they are both operators. And is ||| one
operator, or two operators || + | or | + || or something else?
(Probably something else - a mistake ;-)
