最终，当运行双胞胎一号COBOL程序时，需要查找并识别第二个双胞胎二号。因此，预编译器给这双胞胎“纹”上修改过的时间戳。

Eventually, when twin 1, the COBOL program, runs, it will need to find and identify twin 2. Therefore, the precompiler "tattoos" each twin with a modified timestamp.

与其花时间在xsl上进行多次传递，我宁愿将指令预编译到Templates对象中，完成XSL处理。

Rather than pay for multiple passes over the XSL, I prefer to precompile the instructions into a Templates object and be done with the XSL processing.
