Re: State Alignment and Standard Signals

Doesn't all of this rely on some transport, which will have appropriate 
protocols, that ensures messages are delivered. Clearly this only 
provides guarantees of delivery, as I think is explained below. It does 
not guarantee that the application receiving a message processed it in 
any way. So what would be needed is a "business" message that makes the 
current state of the recipient visible to the sender. The way in which 
this could be done is to use some business relevant messages that form 
a protocol - an understanding if you will.

It does not require that WS-CDL defines these named message types since 
they may be different in different domains. I'm sure that FIXML handles 
this but their approach (their business protocol) is not applicable 
everywhere. It is imbued with their own semantics for a start and so is 
not portable across domains of applicability.

I guess the question that remains to be answered is "why have built-in 
named message types given issues of domain applicability?"

Hence my previous email on ontologies.
