Section 4.5 says:

   The subsequent fragment packets are composed of:

      (1)  The Per-Fragment headers of the original packet, with the
           Payload Length of the original IPv6 header changed to contain
           the length of this fragment packet only (excluding the length
           of the IPv6 header itself), and the Next Header field of the
           last header of the Per-Fragment headers changed to 44.

      (2)  A Fragment header containing:

              The Next Header value that identifies the first header
              after the Per-Fragment headers of the original packet.

              A Fragment Offset containing the offset of the fragment,
              in 8-octet units, relative to the start of the
              Fragmentable Part of the original packet.

It should say:

   The subsequent fragment packets are composed of:

      (1)  The Per-Fragment headers of the original packet, with the
           Payload Length of the original IPv6 header changed to contain
           the length of this fragment packet only (excluding the length
           of the IPv6 header itself), and the Next Header field of the
           last header of the Per-Fragment headers changed to 44.

      (2)  A Fragment header containing:

              The Next Header value that identifies the first header
              after the Per-Fragment headers of the original packet.

              A Fragment Offset containing the offset of the fragment,
              in 8-octet units, relative to the start of the
              "Extension & Upper-Layer Headers" part of the original
              packet.
