Noah,

No, you are right, the specification says instead that untargeted header
blocks are implicitely targeted at the ultimate destination, which I think
brings up another issue (cf. my earlier message to Doug David today).

Thanks for pointing this out, and for the gentle explanation.

BTW, I agree that mustUnderstand, path and routing cannot be discussed
independently.

Jean-Jacques.
