Detailed Description

The field under validation must be yes, on, 1, or true. This is useful for validating "Terms of Service" acceptance. This check will also fail if the input data for the specified field is empty or if the field is not part of the input data.

Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation.
