类名称：XPathContextMajor
方法名：setOrigin

XPathContextMajor.setOrigin介绍

[英]Set the creating expression (for use in diagnostics). The origin is generally set to "this" by the object that creates the new context. It's up to the debugger to determine whether this information is useful. The object will either be an Expression, allowing information about the calling instruction to be obtained, or null.
[中]设置创建表达式（用于诊断）。创建新上下文的对象通常会将原点设置为“this”。由调试器决定这些信息是否有用。对象要么是表达式，允许获取有关调用指令的信息，要么为空。
