Structure-based enum types use values to declare a list of possible values for the type. Each structure-based enum type must have exactly one values clause. If the null keyword is anywhere in the list, instances of the type can be set to null. For more on structure-based enum types, see the section [Enums]. All entries in the values block are implicitly public.
