端点引用将在运行时进行动态组合，从而不需要预先存在的 SCA 导入。

The endpoint reference is dynamically composed at runtime, without requiring a pre-existing SCA import.

注意它没有导入，因为您要利用动态端点机制。

Note that it has no import, since you're going to leverage the dynamic endpoint mechanism.

如果在中介流中使用动态端点，则从连接到用于动态调用的引用的缺省导入生成了首选交互样式。

If a dynamic endpoint is used in the mediation flow, the preferred interaction style is derived from a default import wired to the reference used for the dynamic invocation.
