no synch vs asynch indicator in CPP/CPA

[christopher ferris <chris.ferris@east.sun.com>]

With the removal of the BusinessProtocol and its children
from the tpaML 1.0.6 in our CPP/CPA DTD, we have lost the
ability to attribute synchronous versus asynchronous characteristics
of a delivery channel.

Presently, the BPM specifies synch versus asynch, but IMHO, this
is the WRONG place to specify such a thing as it imposes a
constraint on an implementation.

Rather, I think that a delivery channel and/or the
transport should be declared as having synch or asynch 
characteristics.

This is related to Dale's concerns and (hopefully) investigation
as to the capabilities of the sender which I believe
should also capture some aspect of the synch vs asynch nature
of the initiating (sending) Party's delivery channels.

The distinction as I see it is that the BP should be
independent of an implementation, but an implementation
that supports a BP would be engineered so as to provide for
either response pattern according to its needs.

Comments?

Cheers,

Chris
