SBVR11 — Note for individual concept does not follow from the Definition

Clause 8.1.1

Concept: individual concept

The Definition of 'individual concept' is:
concept that corresponds to only one object [thing]

The Note says:
"each referring individual concept has exactly one and the same instance in all possible worlds"

"Corresponds to only one object" (in any possible world) is not at all the same thing as "corresponds to exactly one and the same object in all possible worlds". One of the definition and the Note should be corrected. I would prefer changing the definition to match the note.

Note also that changing the definition means that "the President of the United States" is an 'individual concept' that denotes an office, but not a person. And the concept "the person who is President of the United States" is not an 'individual concept'.

Change the definition to match the note
