Section 2.1, pg.5 says:

   Prefix Length

      A sixteen-byte field containing the Mobile IPv6 Network Prefix;
      all insignificant (low-order) bits (beyond the Prefix Length) MUST
      be set to 0 by the originator of the option and ignored by the
      receiver.

   Mobile IPv6 Network Prefix

      A sixteen-byte field containing the Mobile IPv6 Network Prefix

It should say:

   Prefix Length

|     Indicates the prefix length of the prefix included in the Mobile
|     IPv6 Network Prefix field.  A value of 255 indicates that a link-
|     local address is included in the Mobile IPv6 Network Prefix field.

   Mobile IPv6 Network Prefix

|     A sixteen-byte field containing the Mobile IPv6 Network Prefix;
|     all insignificant (low-order) bits (beyond the Prefix Length) MUST
|     be set to 0 by the originator of the option and ignored by the
|     receiver.

Notes:

The replacement text apparently has been placed into the wrong
field explanation.
The text presented for "Prefix Length" is the text that should
be specified for "Mobile IPv6 Network Prefix"; the correct text
for "Prefix Length" (as shown above) is borrowed from Section 2.2.
