+/** |
+ * The nsIInterfaceRequestor interface defines a generic interface for |
+ * requesting interfaces that a given object might provide access to. |
+ * This is very similar to QueryInterface found in nsISupports. |
+ * The main difference is that interfaces returned from GetInterface() |
+ * are not required to provide a way back to the object implementing this |
+ * interface. The semantics of QI() dictate that given an interface A that |
+ * you QI() on to get to interface B, you must be able to QI on B to get back |
+ * to A. This interface however allows you to obtain an interface C from A |
+ * that may or most likely will not have the ability to get back to A. |
