+ *
+ * @brief Defines a factory that creates new <ACE_Association>s passively.
+ *
+ * The <ACE_SOCK_SEQPACK_Acceptor> has its own "passive-mode" socket.
+ * This serves as a factory to create so-called "data-mode"
+ * sockets, which are what the <ACE_SOCK_SEQPACK_Association> encapsulates.
+ * Therefore, by inheriting from <ACE_SOCK>, <ACE_SOCK_SEQPACK_Acceptor>
+ * gets its very own socket.
