This document defines the semantics for grouping the associated
source and FEC-based (Forward Error Correction) repair flows in the
Session Description Protocol (SDP).  The semantics defined in this
document are to be used with the SDP Grouping Framework (RFC 5888).
These semantics allow the description of grouping relationships
between the source and repair flows when one or more source and/or
repair flows are associated in the same group, and they provide
support for additive repair flows.  SSRC-level (Synchronization
Source) grouping semantics are also defined in this document for
Real-time Transport Protocol (RTP) streams using SSRC multiplexing.
