Message in Korean (한국어)
union 데이터 형식은 atomic 또는 list 데이터 형식에서 파생되어야 합니다.
Unlocalized message
It is an error if a union type has a member with variety union and this member cannot be substituted with its own members. This may be due to the fact that the union member is a restriction of a union with facets.
