Section 6.4 says:

   -  Forging a (*,*,RP) join presents a possibility for a denial-of-
      service attack by causing all traffic in the domain to flow to the
      PMBR issuing the join.  (*,*,RP) behavior is included here
      primarily for backwards compatibility with prior revisions of the
      spec.  However, the implementation of (*,*,RP) and PMBR is
      optional.  When using (*,*,RP), the security concerns should be
      carefully considered.

It should say:

      service attack by causing all traffic in the domain to flow to the
      PMBR issuing the join.  (*,*,RP) behavior is included here
