M3UA : How to deal whit Unexpected ASPSM/ASTM Message (Jacky Chen)

Thanks,brain

but new questions are :
1: for  question One,when received unexpected ASP INACTIVE Ack message,ASP
should Send ASP-DWON Message to
return itself to its previous state???

2: for question Two: why not discard the unexpected  ASP UP ACK or ASP
INACTIVE ACK OR ASP ACTIVEACK
  When ASP IS IN ASP-DOWN Status?
because when ASP ENTER ASP INACTIVE When received  unexpected ASP Up Ack
message,the AS Contain THE ASP maybe enter into AS-INATIVE Status
temporarily ,This is not reasonable.

i think in rfc4666,it need to explain how to deal with every unexpected
ASPSM/TM Message in every as/asp status .
