Section 8 says: 

   Options:

      This field encodes binary indications of the presence and
      significance of any options.  It also directly encodes some
      options.

      bit 0 set => One or more Option Extensions are present

      bit 1 set => One or more Options are network-significant

         Note that this bit is clear when OPT_FRAGMENT and/or
         OPT_JOIN are the only options present.

      bit 6 set => Packet is a parity packet for a transmission
	 group
      of variable sized packets (OPT_VAR_PKTLEN).  Only present
	 when
      OPT_PARITY is also present.

      bit 7 set => Packet is a parity packet (OPT_PARITY)

      Bits are numbered here from left (0 = MSB) to right (7 =
	 LSB).

      All the other options (option extensions) are encoded in
      extensions to the PGM header.

It should say:

Section 9.2.4 says: 

Option Length = 12 octets

It should say:

Option Length = 16 octets

Notes:

Every option packet has a certain length including the option header itself. OPT_LENGTH, OPT_NAK_LIST and OPT_JOIN have the length correctly counted WITH the header length (4B) but OPT_FRAGMENT has 4*4B so the total length should be 16 octets.

Section 1.2.5. says: 

If receivers are several hops
   removed from the first PGM network element, the efficacy of NAK
   suppression may degrade.

It should say:

If receivers are several hops
   away from the first PGM network element, the efficacy of NAK
   suppression may degrade.

Notes:

This is simply a stylistic suggestion in the wording choice.
