which在这个句子里起的作用是什么
In practical terms,what SubjectConfirmation says is "these are the conditions under which an attesting entity (somebody trying to use the assertion) is permitted to do so".
其中which的作用,我理解有三：
1.which 指的就是SubjectConfirmation
2.under which引导的状语从句
3.which 指的是conditions
请问那种对,或者是有另外的解释,最好帮说明一下原因
