public interface Descriptor

Interface that adds a set of string-based, normalized properties for describing DDL information.

Typical characteristics of a descriptor are: - descriptors have a default constructor - descriptors themselves contain very little logic - corresponding validators validate the correctness (goal: have a single point of validation)

A descriptor is similar to a builder in a builder pattern, thus, mutable for building properties.
