All,

another small update to address the comment from Vincent providing a pointer to the framework on the matter of non-consecutive sequence numbers.

>   This document describes Fully-Specified Forward Error Correction
>   (FEC) Schemes for the Raptor and RaptorQ codes and their application
>   to reliable delivery of media streams in the context of FEC
>   Framework.  The Raptor and RaptorQ codes are systematic codes, where
>   a number of repair symbols are generated from a set of source symbols
>   and sent in one or more repair flows in addition to the source
>   symbols that are sent to the receiver(s) within a source flow.  The
>   Raptor and RaptorQ codes offer close to optimal protection against
>   arbitrary packet losses at a low computational complexity.  Six FEC
>   Schemes are defined, two for protection of arbitrary packet flows,
>   two that are optimised for small source blocks and another two for
>   protection of a single flow that already contains a sequence number.
>   Repair data may be sent over arbitrary datagram transport (e.g.  UDP)
>   or using RTP.
