 *  GraphQL SDL Enum Extensions
 * --------------------------------------------------------------------------
 *
 * Enum type extensions are used to represent an enum type which has been
 * extended from some original enum type. For example, this might be used
 * to represent additional local data, or by a GraphQL service which is
 * itself an extension of another GraphQL service.
