Each FS represents one session that has learnedinfo about this FEC.  More then one piece of info can be learned by a sessionfor a particular FEC, so each FS can have a list of Attr, which is all of theinfo learned about this FEC by this session.  Take note that each FEC entryhas a list of FS for upstream and downstream sessions.
