Section 9 says:

IP6-multicast =       hexpart [ "/" integer ]

IP6-address =         hexpart [ ":" IP4-address ]

hexpart =             hexseq / hexseq "::" [ hexseq ] /
                              "::" [ hexseq ]

hexseq  =             hex4 *( ":" hex4)

hex4    =             1*4HEXDIG

It should say:

IP6-multicast =       IP6-address [ "/" integer ]

IP6-address =                                      6( h16 ":" ) ls32
                          /                       "::" 5( h16 ":" ) ls32
                          / [               h16 ] "::" 4( h16 ":" ) ls32
                          / [ *1( h16 ":" ) h16 ] "::" 3( h16 ":" ) ls32
                          / [ *2( h16 ":" ) h16 ] "::" 2( h16 ":" ) ls32
                          / [ *3( h16 ":" ) h16 ] "::"    h16 ":"   ls32
                          / [ *4( h16 ":" ) h16 ] "::"              ls32
                          / [ *5( h16 ":" ) h16 ] "::"              h16
                          / [ *6( h16 ":" ) h16 ] "::"

h16 =                 1*4HEXDIG

ls32 =                ( h16 ":" h16 ) / IP4-address

Notes:

Correct IPv6 ABNF.
