- // 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.
