-    // Feeds come in various content types, which our feed sniffer coerces to

-    // different data types, e.g. news/blogs (traditional feed), video/audio
-    // (podcasts) and photos (photocasts, photostreams). Each of these is 
-    // different in that there's a different class of application suitable for
-    // handling feeds of that type, but without a content-type differentiation
-    // it is difficult for us to disambiguate.
-    // 
-    // The other problem is that if the user specifies an auto-action handler
-    // for one feed application, the fact that the content type is shared means 
-    // that all other applications will auto-load with that handler too, 
-    // regardless of the content-type. 
-    //
-    // This means that content-type alone is not enough to determine whether
-    // or not a feed should be auto-handled. This means that for feeds we need
-    // to always use this stream converter, even when an auto-action is 
-    // specified, not the basic one provided by WebContentConverter. This 
-    // converter needs to consume all of the data and parse it, and based on
-    // that determination make a judgment about type. 
-    //
-    // Since there are no content types for this content, and I'm not going to
-    // invent any, the upshot is that while a user can set an auto-handler for
-    // generic feed content, the system will prevent them from setting an auto-
-    // handler for other stream types. In those cases, the user will always see
-    // the preview page and have to select a handler. We can guess and show 
-    // a client handler, but will not be able to show web handlers for those
-    // types.
-    //

-    // auto-handlers can be set and we should obey them.
