Clarfication regarding ReceiptAcknowledgments

[Himagiri Mukkamala <himagiri@sybase.com>]

Section 6.6.2 describes in general that responding role signals
exception to requesting role and terminate. Requesting role can
use a notification of failure to indicate exception to responder role.

In the event of a missing receipt acknowledgement from the
requesting role arising from the receipt of a responding document,
how should the responding role signal an exception to the
requesting role? Are we assuming that the MSH on the resquesting
role would detect a failure to deliver the receipt and send a
notification of failure to the responder role?

Similarly, is it the intention of the spec that NRR does not apply in
this
situation? It seems to me that the responding role should also
save a signed copy of the receipt acknowledgement from the
requesting role that it has received the responding document.

Can you please clarify the above or if this has been addressed, please
point me to the appropriate locations.

Thanks
Michael
