Hi Claudio,

One clarification question to your comment ...

Why are you saying that there will be an error in the regular AS_PATH ? 
As far as I can see the above quote refers only to AS4_PATH.

The motivation is that instead of dropping the session or treating as 
withdraw robust BGP speaker can just remove the unexpected bad elements 
from AS4_PATH. In that respect this paragraph seems to add value and 
should be kept.

Rgs,
R.
