An enumeration is a data type whose values are enumerated in the model as enumeration literals.
Description
Constructs::Enumeration reuses the definition of Enumeration from Basic. It adds a specialization to Constructs::DataType.Enumeration is a kind of data type, whose instances may be any of a number of predefined enumeration literals. It is possible to extend the set of applicable enumeration literals in other packages or profiles.

Semantics
The run-time instances of an Enumeration are data values. Each such value corresponds to exactly one EnumerationLiteral.
Notation
An enumeration may be shown using the classifier notation (a rectangle) with the keyword «enumeration». The name of the enumeration
is placed in the upper compartment. A compartment listing the attributes for the enumeration is placed below the name compartment.
A compartment listing the operations for the enumeration is placed below the attribute compartment. A list of enumeration
literals may be placed, one to a line, in the bottom compartment. The attributes and operations compartments may be suppressed,
and typically are suppressed if they would be empty.
