可以为其定义消息序列，表明所需(有效)的操作顺序。

Its message sequence could be defined to indicate the required (valid) ordering of operations.

调用方可以通过状态模型计算有效的操作序列。

Callers can compute valid sequences of operations from the state model.

但将XML文档的序列拆成与有效性类相对应应该是可能的。

But it should be possible to de-serialize an XML document to corresponding validity classes.

And so this begs the question, even in the context of these cups, how can we possibly do better if at the end of the day in order to figure out if two cups or if two people or if two ints inside of an array are bigger or smaller than one another it feels like we have to do this comparison work anyway.

这样就回避了问题的实质,从这些杯子的相互关系来看，我们怎样才能更有效地,找出序列中比其他元素,都大或都小的两个杯子，两个人，两个数,看起来我们无论如何都得,做比较的工作。
