modulename规范声明包装器将在什么模块中。
The modulename specification states what module the wrapper will be in.
不过,值得一提的是,J2EE 1.4规范声明能够在不进行更改的情况下运行1.2和1.3版本的应用程序。

Thus, it is important in which order you declare attribute evaluation specifications.
And just to look ahead a little bit, you could easily imagine that I might want to not just put a statement in there, what the specs are, I might want to put some constraints. Some specific things to check for, to make sure that you're calling the code right.
这不仅是抽象的概念还有规范的概念,我们再往前看看,你可以简单的想象得到,我不仅仅是想在这里加一个声明,这些规范说明中我还想加一些约束,我们要注意一些特殊的事情。
