Subject: Callbacks are correlated at interface level, not operation level

From assembly defintions, the callback inteface operations are not
correlated to individual operations in the service interace.  All that is
required is the address to the callback interface port, corresponding to
the service interface.

I do not understand why we are talking about correlating callback
operation request messages with a specific service interface operation
request message.

Example Bidir Interace

Service interface  PurchaseOrder
   PostPO (in proposedPO type PO, out agreedPO type PO)
   ammendPO (in proposedAmmend type PO, out agreedAmmend type PO)

Callback interface Invoice
   PostInvoice (in proposedInvoice type Invoice, out agreedInvoice type
   ammendInvoice (in proposedAmmend type Invoice, out agreedAmmend type

Question, which service interface operation request message should the
message id (or callback id) on the callback “request” message  for an
ammendInvoice operation invocation refer to?
