Section 4.3 says:

Sequence Number

      The sequence number for this packet.  For Keyed MD5
      Authentication, this value is incremented occasionally.  For
      Meticulous Keyed MD5 Authentication, this value is incremented for
      each successive packet transmitted for a session.  This provides
      protection against replay attacks.

It should say:

Sequence Number

      The sequence number for this packet.  For Keyed MD5
      Authentication, this value is incremented (by one) occasionally.  For
      Meticulous Keyed MD5 Authentication, this value is incremented by one for
      each successive packet transmitted for a session.  This provides
      protection against replay attacks.

Notes:

This change clarifies the amount by which the sequence number is incremented.

Section 6.8.4 says:

If Demand mode is active, and a period of time equal to the Detection
Time passes after the initiation of a Poll Sequence (the transmission
of the first BFD Control packet with the Poll bit set), the session
has gone down

It should say:

If Demand mode is active, and a period of time equal to the Detection
Time passes after the initiation of a Poll Sequence (the transmission
of the first BFD Control packet with the Poll bit set),and without 
receiving a BFD Control packet with the Final (F) bit set from the
remote system, the session has gone down

Notes:

If has received BFD Control packet with the Final (F) bit set from the
remote system, the session will not gone down
