UG does not say that adding duplicate attributes is not allowed

UG did not state that duplicate register number is not allowed but when I tested adding a student with same register number as existing student it gives an error

Team's Response

Justification for low: In actual scenario, unlikely that you will have students that have the same phone number or same email, or same class and register number.

Items for the Tester to Verify

:question: Issue severity

Team chose [severity.Low] Originally [severity.Medium]

• [x] I disagree

Reason for disagreement: Although having the same phone number or same email, or same class and register number is uncommon, typos and scenarios like class mergers or reassignments of classes make it more common. Without clear documentation, users are left guessing why their input is invalid. This causes occasional inconvenience that directly affects normal operations, even if the product remains functional overall.
