Neil,

guess that tht is a fair question, it should be looked into,
but I guess that it is out of scope for an update of the
LDP spec. (I didn't say "implemenation specific :) ). For
communication between LDP peers it is my take that we can
trust TCP, after all that was one of the reasons chosing
TCP.

Now, if the protocol exchange information in a correct
manner, but one implementation creates a label mapping
that is errornous, this is not something we can address
in the protocol specification, is it?
