That works fine for malformed attributes. It blows chunks for legally formed but unknown attributes - how would you ever deploy a new attribute?By making it optional. Seems to me that's pretty well covered by the Path Attributes section of the RFC. A bad attribute isn't simply unknown, it's malformed. My apologies for not wording that more precisely. I do see the wisdom of fine-grained control of this behavior. I'm just saying, it'd be nice if we could have correct behavior on the basics in the first place. :)
