Message in Chinese (Simplified) (中文(简体))
多重性在关系“<var>Y</var>”中的 Role“<var>X</var>”中无效。因为 Dependent Role 中的所有属性都可以为 null,Principal Role 的多重性必须为“0..1”。
Unlocalized message
Multiplicity is not valid in Role '<var>X</var>' in relationship '<var>Y</var>'. Because all the properties in the Dependent Role are nullable, multiplicity of the Principal Role must be '0..1'.
