Section 3.2,1st para says:

   To ensure that a type 1 Encoded-Source Address is not sent to a PIM
   neighbor that does not understand this encoding, a new PIM Hello
   option, the "Join Attribute" option, is defined.  This option MUST be
   included in the PIM Hellos of any PIM router that is willing to
|  receive type 1 Encoded-Source Address.  A PIM router MUST NOT send a
                                        ^
   type 1 Encoded-Source Address out any interface on which there is a
   PIM neighbor that has not included this option in its Hellos.  (Even
|  a router that is not the upstream neighbor must be able parse the
                                                          ^
   packet in order to do Join suppression or overriding.)

It should say:

   neighbor that does not understand this encoding, a new PIM Hello
   option, the "Join Attribute" option, is defined.  This option MUST be
   included in the PIM Hellos of any PIM router that is willing to
|  receive type 1 Encoded-Source Addresses.  A PIM router MUST NOT send
                                        ^^^
   a type 1 Encoded-Source Address out any interface on which there is a
   PIM neighbor that has not included this option in its Hellos.  (Even

                                                          ^^^^
   packet in order to do Join suppression or overriding.)
