This document describes how to adapt the Session Description Protocol
(SDP) to express one or more source addresses as a source filter for
one or more destination "connection" addresses.  It defines the
syntax and semantics for an SDP "source-filter" attribute that may
reference either IPv4 or IPv6 address(es) as either an inclusive or
