A question on JEP 455 specification

[Archie Cobbs]

Sounds like “which” should be “that” instead.

“Which” is used to incidentally add descriptive information without
affecting the logic of a statement.

“That” is used to narrow the identity of something (and therefore exclude
other possibilities), which (no pun intended) obviously does affect the
logic.

“I have a car which is blue”

“I have the car that is blue”
