Nitin,
In section 2.3 it says:
" A route is essentially a match condition and an action following the
   match.  The match condition specifies the kind of route (IPv4, MPLS,
   etc.) and the set of fields to match on.  Figure 3 represents the
   overall contents of a route ... This document specifies the following match types:

   o  IPv4: Match on destination IP address in the IPv4 header

   o  IPv6: Match on destination IP address in the IPv6 header 
...
  o  IP multicast: Match on (S, G) or (*, G), where S and G are IP
      prefixes"

However, section 6 defines:
"<match> ::= <route-type> (<ipv4-route> | <ipv6-route> | <mpls-route> |
                            <mac-route> | <interface-route>)
  <route-type> ::= <IPV4> | <IPV6> | <MPLS> | <IEEE_MAC> | <INTERFACE>

  <ipv4-route> ::= <ip-route-type>
                   (<destination-ipv4-address> | <source-ipv4-address> |
                    (<destination-ipv4-address> <source-ipv4-address>)) ...

  <ipv6-route> ::= <ip-route-type>
                   (<destination-ipv6-address> | <source-ipv6-address> |
                    (<destination-ipv6-address> <source-ipv6-address>))
"
The terms using source address are probably meant for multicast, if this is the intention it should be changed to match the definition:
(S, G) or (*, G).

Thanks,
Yael
