Message in Chinese (Simplified) (中文(简体))
如果在单个成员上指定了多个自定义特性，则只有其中一个特性必须具有显式“<var>X</var>”属性；但如果不止一个特性具有显式“<var>X</var>”，则所有值都必须匹配。
Unlocalized message
If multiple custom attributes specified on a single member only one of them have to have explicit '<var>X</var>' property, however if more that one attribute has the explicit '<var>X</var>', all values have to match.
