Clemens szyperski discusses the distinction between interface and implementation inheritance in his excellent book Clemens szyperski在他的一篇優秀書籍
Because interfaces do not support implementation inheritance , the pattern that applies to classes does not apply to interfaces 由于接口不能支持繼承,用于類的模式不能用于接口。
This silence is odd , considering that there is a simple mechanism in xml schema that can be used to provide the same effect as implementation inheritance : the extension mechanism 這種沉默是暫時的,因為xml schema中有一種簡單的機制可以用來達到與實現繼承同樣的目的:擴展機制。
