+/**
+ * The nsIWebProgress interface is used to add or remove nsIWebProgressListener
+ * instances to observe the loading of asynchronous requests (usually in the
+ * context of a DOM window).
+ *
+ * nsIWebProgress instances may be arranged in a parent-child configuration,
+ * corresponding to the parent-child configuration of their respective DOM
+ * windows.  However, in some cases a nsIWebProgress instance may not have an
+ * associated DOM window.  The parent-child relationship of nsIWebProgress
+ * instances is not made explicit by this interface, but the relationship may
+ * exist in some implementations.
+ *
+ * A nsIWebProgressListener instance receives notifications for the
+ * nsIWebProgress instance to which it added itself, and it may also receive
+ * notifications from any nsIWebProgress instances that are children of that
+ * nsIWebProgress instance.
