RegularExpressionAttribute.IsValid has incorrect Exceptions section

[daiplusplus]

• RegularExpressionValidator.IsValid does not throw ValidationException
• The documentation says it throws ArgumentException for the regex pattern even though that's not an actual argument to the public method.
• Also, the documentation doesn't explain how an argument typed as Object? (which is not a String) can be validated by a regular expression - or what happens to null arguments.
