/**
 * Creates a new scheme.
 * Whether the created scheme allows for layered connections
 * depends on the class of {@code factory}.
 *
 * @param name      the scheme name, for example "http".
 *                  The name will be converted to lowercase.
 * @param factory   the factory for creating sockets for communication
 *                  with this scheme
 * @param port      the default port for this scheme
 *
 * @deprecated (4.1)  Use {@link #Scheme(String, int, SchemeSocketFactory)}
