Subject: Re: initial draft of CPP-CPA Specification

Please forward to BP since I cannot post to that list.

I would think that the order should be:

>   Transport
>   Message Handler
>   Collaboration Manager
>   Transaction Manager
>   Adapter
>   Internal business app

The "Transaction manager" is only invoked if it has been
sanctioned/vetted by the Collaboration Manager.
The "Transaction Manager" invokes the appropriate
Adapter for the internal business application
and would be responsible for the response
(if any) and any signals that are required.

BTW, you left out Network as the top (or bottom)
of the stack;-)

My $0.02,
