-- Enum_Pos_To_Rep (Node23)
--- Defined in enumeration types (but not enumeration subtypes). Set to
--- Empty unless the enumeration type has a non-standard representation
--- (i.e. at least one literal has a representation value different from
--- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
--- array constructed when the type is frozen that maps Pos values to
--- corresponding Rep values. The index type of this array is Natural,
--- and the component type is a suitable integer type that holds the
--- full range of representation values.

+-- entity for an array constant built when the type is frozen that maps
+-- Pos values to corresponding Rep values, whose index type is Natural
+-- and whose component type is the enumeration type itself; or else, if
