Section 6.4.3 says:

   A special case of the DAO message, termed a No-Path, is used in
   Storing mode to clear Downward routing state that has been
   provisioned through DAO operation.  The No-Path carries a Target
   option and an associated Transit Information option with a lifetime
   of 0x00000000 to indicate a loss of reachability to that Target.

It should say:

   A special case of the DAO message, termed a No-Path, is used in
   Storing mode to clear Downward routing state that has been
   provisioned through DAO operation.  The No-Path carries a Target
   option and an associated Transit Information option with a lifetime
   of 0x00 to indicate a loss of reachability to that Target.

Notes:

The Path Lifetime field of the Transit Information option is a 8-bit field. Using 0x00000000 here would indicate a 32 bits encoding and is misleading.
