Create a composite class representing a Restriction Document, containing multiple Restrictions. This class must expose a general purpose interface for validating all contained restrictions against a Restriction Environment. Create a composite class representing a set of Restriction Documents. This class must expose a general purpose interface for validating that any contained Restriction Document is met, given a Restriction Environment. Create a supercomposite class representing a set of sets of Restriction Documents, which validates that every set has at least one Restriction Document whose conditions are met. Write a set of unit tests for these classes.
