/**
 * EnumerationLiteral instances describe the enumeration identifiers, and possibly
 * the
 *
 * values, associated with an emerated data type. Enumeration identifiers are
 * contained
 *
 * in the name attribute derived from the EnumerationLiteral instance?s
 * ModelElement superclass.
 *
 *
 *
 * EnumerationLiteral instances may also be used to define expression-based values
 * such as ranges. To do so, simply state the membership expression in the
 * instance?s value. For example, a range literal can be created by setting the
 * value attribute to "m..n", where m represents the lower bound of the range, and
 * n, the upper bound. In this way, ranges and other more complicated expressions
 * can be intermixed with simple
 *
 * enumeration literals. For example, an enumeration might contain the literals
 * "1", "2", "4..7", and "> 10".
 *
 *
 *
 * Consequently, a simple range data type can be created with an Enumeration
 * instance that owns a single EnumerationLiteral instance. For example, a data
 * type for positive integers could be created as shown in the following instance
 * diagram. A model attribute of this data type might then be declared as "posInt
 * : PositiveInteger".
