Hi.  We have found the first bug (;-)) in the revised 2level signaling
draft.  The bug is in the definitions of signaling messages xSig()
on page 17: all the messages that carry an SAPUid but NOT an SAPU
should carry a LIST of SAPUids ("SAPUid-list").  This is a signficant
efficiency hack.  It allows a single REFRESH message, in particular,
to refresh a whole boatload of state in one message.  Here is the
revised table of messages:

           xSig(NEW, h-src, SAPUid, SAPU, R)
           xSig(MOD, h-src, SAPUid, SAPU, old-SAPUid, R)
           xSig(TEAR, h-src, SAPUid-list)
           xSig(REFRESH, h-src, SAPUid-list, R)
           xSig(ACK, h-dest, SAPUid-list)
           xSig(NACK, h-src, SAPUid-list)
           xSig(INFO, h-src, SAPUid, SAPU)
           xSig(EVENT, h-src, SAPUid, SAPU)
           xSig(CHALLENGE, h-src, challenge-object)
           xSig(RESPONSE, h-src, challenge-object)
           xSig(ERROR, h-dest, SAPUid-list)
