If a speaker talks to a crowd there may be now confirmation that all words has been received. If a sender sends an email to a court or an application there may be no conformation comming back and if the email actually reached the intended addressee if will be recorded. With regards to enforceable a repudiation example may be of interest. If a originator sends a data message to an indented addressee but the addressee claims that he didnt get the message. a) If the sender gets access to the receivers infoprmation system , through court order or otherwise, and finds an exact replica of the data message then it will be difficult to continue to claim that the data message wasnt received. b) If in a automated environment a Receipt data message is sent from the addresse back to originator with signature, ref to data message, date, etc. it will be difficult to claim that the data message was received. May the addressee can claim that the signature key was stolen and it was resonable that the originator should have know about the theft. c) If an intelligent firewall stores all incomming data messages for future reference and also does a XML Schema validation on the payload then this log may be used to claim that the data message was received. d) ebXML MessageService Handler signed <Acknowledge> SOAP header may be used to claims Reach. One important aspect is that it is Not resonable that a sender should care about or be responsible for how a receiver has constructed its information system and in case c) if the data message is lost after the firewall then the reception failed under the recivers care. If a reciever has data message (reach event occured) and waits to send a ReciptAck until a deadline of some kind has passed then which is the most resonable outcome ..? 1. data message reached the indended addressee and it should be counted as a "valid" data message 2. Reciept Ack was never sent in time so the data message should be counted as not have been sent. thanks /anders
