At the Redwood City meeting last May we came to general agreement that 
the protocol
requires persistence to work (e.g, persistence of ids for duplicate 
elimintation, persistence of
message contents for ordered delivery).  However, some users might we 
willing to accept
protocol failure under specific circumstances which are agreed witht the 
system supplier (e.g, if the battery is not kept charged on a cell 
phone, it might loose its "persistence" capability).

Thus this preagreed limit for persistence time is subject to user 
contract, since it involves an
argreement as to what conditions are acceptable for tolerating protocol 
failure.

I hope this helps.
