/**
 * A data type is a type whose values have no identity (i.e., they are pure
 * values). Data types include primitive built-in types (such as integer and
 * string) as well as definable enumeration types.
 *
 *
 *
 * In the metamodel, a DataType defines a special kind of Classifier in which
 * operations are all pure functions (i.e., they can return data values but they
 * cannot change data values, because they have no identity). For example, an
 * "add" operation on a number with another number as an argument yields a third
 * number as a result; the target and argument are unchanged.
 *
 *
 *
 * A DataType is a special kind of Classifier whose instances are primitive
 * values, not objects. For example, integers and strings are usually treated as
 * primitive values. A primitive value does not have an identity, so two
 * occurrences of the same value cannot be differentiated. Usually, DataTypes are
 * used for specification of the type of an attribute or parameter.
