Message in Chinese (Simplified) (中文(简体))
MC6021: 不能在该标记上指定 <var>X</var>:FieldModifier，因为它不具有 <var>X</var>:Name 或 Name 属性集，或者该标记是本地定义的且具有 Name 属性集，而这种情况是不允许的。
Unlocalized message
MC6021: <var>X</var>:FieldModifier cannot be specified on this tag because it has either no <var>X</var>:Name or Name attribute set, or the tag is locally defined and has a Name attribute set, which is not allowed.
