I propose the inclusion of a new validator based on the Specified values validator. The description would be:

Verifies that the specified component contains a defined value(s) and excludes any other values

This compares to the Specified values validator:

Verifies that the specified component contains a defined value

The purpose of the new Specified values (exclusive) validator is to provide alternative functionality regarding multi-select lists and to resolve ambiguity regarding the function of the Specified values validator.

I have a patch which I will post shortly.
