샘플 코드
지정된 예에서 CustomChangeOrder는 WTChangeOrder2의 모델링된 하위 유형입니다. CustomChangeOrder는 서식 있는 텍스트 속성 longDescription을 포함하도록 수정됩니다. 또한 단순 텍스트 속성 myAttribute 및 해당하는 서식 있는 텍스트 속성 myLongAttribute가 모델링된 하위 유형에 추가됩니다. description 및 myAttribute 등의 단순 텍스트 설명 속성을 longDescription 및 myLongAttribute 등의 서식 있는 텍스트 설명 속성으로 변환하기 위해 지정된 대로 CustomChangeOrderDelegate 위임이 작성됩니다.
