    <para>Allocates a new stream, associating it with the given argument (connection parameter)
        metadata. The relevant connection parameter data will later be sent along the stream with
        blob instructions. If sent by the client, this data will be the desired new value of the
        connection parameter being changed, and will be applied if the server supports changing that
        connection parameter while the connection is active. If sent by the server, this data will
        be the current value of a connection parameter being exposed to the client.</para>
