Section 3.1 says:
Use of the attribute is, however, not restricted to the construction of source trees. It may also be used to construct a shared tree. In this case, the RPF Vector TLV contains the IP address of a Rendezvous Point (RP).
It should say:
Use of the attribute is, however, not restricted to the construction of source trees. It may also be used to construct a shared tree. In this case, the RPF Vector TLV contains the IP address of an edge router on the path to the Rendezvous Point (RP).
Notes:
For a source tree, as per section 3.0, RPF Vector TLV contains the IP address of edge-1 which is to be used to reach the source. Similarly, for shared tree, RPF vector TLV should contain the IP address of the edge router which is to be used to reach RP.

F-bit Forward Unknown TLV. If this bit is set, the TLV is forwarded regardless of whether the router understands the Type. If the TLV is known, the F bit is ignored. E-bit: End of Attributes. If this bit is set, then this is the last TLV in the stack.
Notes:
RFC 5384 defined the Join Attribute for PIM.
RPF vector is one such Join attribute.
RFC 5384 defined the format for Join Attributes to use the F-bit and E-bit.
This change aligns the terminology with RFC 5384 and aligns the bit numbers in the figure.
There is no change to bits on the wire, procedures, or implementation details.
