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.
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.
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.
