If there has to be an explanation that the name chosen for something means
something else everywhere else, then the wrong name has been chosen.

>From 4.6.4 sh:xor
"Note that despite the name, the semantics of sh:xor for cases with 3 or more
shapes are different from an exclusive or in the mathematical sense. The
general definition of exclusive or makes it true only when an odd number of
inputs are true, while the SHACL definition of sh:xor relies on exactly one
semantics."
