Data Validation in the ITRDS is comprised of four parts.

1. IT_DATA default validation
2. Promatix Validation
3. Rams Pro formcode validation
4. Rams Pro Data Dictionary validation code

All of them are hooked into either the "Save" method of the IT_DATA class or the "DELETE" method of the
IT_DATA class. All the ITRDS specific logic for validation is kept in the RP_DATACORE class and it's child
classess. Hence to document this functionality I have put documentation in the classes and exposed that
here. This is the top level of the documentation and nodes below show the flow.
