hi,

I have been trying to put together a webservices stack, mainly using as a
template the "stack" (as reported by james snell at IBM developerworks)
which came out of the W3C webservices workshop.

It reads

1. internet - IPv4 Ipv6
2. transport - http etc
3. messaging - soap, xml protocol
4. routing reliability transactions  ???
5. workflow, discovery, registries - UDDI ebXML registry, WSFL, XLANG
6. service negotiation - trading partner agreements

Layers 2-6 - security, process management, QoS

I would like to hear any comments anyone has on this, since I want to get it
right and have some concerns.

One of my concerns is routing and reliability in layer 4. I think these
might be generic and not sufficient to be worth mentioning, particularly
since they come under management also. This would leave layer 4 for
transactional languages such as XAML, and the business transaction protocol.
Then in layer 5 you could describe a webservice as "transactional".

You can see it in colour at
