Additionally, it should have a `lowest_layer_type` member type, and a `lowest_layer` member function, returning a `lowest_layer_type&`, following Asio's layered stream model. Additionally, `lowest_layer_type` should inherit from an instantiation of [asioreflink basic_stream_socket basic_stream_socket]. The types `boost::asio::basic_stream_socket` and `boost::asio::ssl::stream>` meet these requirements. [endsect]
