+ * some attributes of InputEvent.  It would be nice if this was in
+ * nsContentUtils.h, however, it needs to include StaticRange.h for declaring
+ * this.  That would cause unnecessary dependency and makes incremental build
+ * slower when you touch StaticRange.h even though most nsContentUtils.h users
+ * don't use it.  Therefore, this struct is declared in separated header file
