These classes contain the source code for the class validation events that includes the logic that is used to validate fields and the document as a whole, as well as to control the behavior of the Verifier form.
You can add new validation events that correspond to newly created fields on these classes. These extra events are created at the end of the existing code in the area marked in the script.
Do not make any changes to the existing code. Doing so causes the solution to stop operating.
