Hello Emil, the "Home Address Option" is borrowed from MIPv6, and hence is always included with the FBU. What would you like to see clarified? "Home Address Option" => "Home Address Destination Option" in 6.3.1? This might be possible in the final proof-reading, if not we can address it in the next avatar.
