Just out of curiosity, at what point will we as operators rise up against the ivory tower protocol designers at the IETF and demand that they add a mechanism to not bring down the entire BGP session because of a single malformed attribute? Did I miss the memo about the meeting?
I guess you did.

rfc 4893 (4 octet as numbers) leverages the assumption that you can send the as4_path attribute and that even router's that don't understand it will forward it. given that 4 byte as numbers exist in the internet and many non-4byte aware routers exist, that seems like a reasonable assumption.
