BPEL

BPEL's capacity goes beyond the range of traditional, definitional XML types.

BPEL的能力超过了传统的 、 定义好的XML类型的范畴.

As a rule of thumb, wherever there is "system invocation logic embedded in the BPEL implementation" we expect the divergence to be high.

从纯实践经验的角度看，我们认为，凡是“在BPEL实现中嵌入了系统调用逻辑”时，上述二者的差异都会非常明显。

However, the security aspect of access control is explicitly mentioned to be outside the scope of BPEL.

然而, BPEL缺乏访问控制方面的安全性考虑.

Normally, if you need some minor function within the BPEL processes, such as a simple calculation, you can embed this code in a Java snippet inside the BPEL process.

通常，如果在BPEL流程内需要较小的功能（如简单的计算），可以将此代码嵌入到BPEL流程内的Java代码片段中。
