Info & Exchange Models added to Service Description Model

["Jeffrey A. Estefan" <jeffrey.a.estefan@jpl.nasa.gov>]

Danny and Ken,

I'm in the process of updating the Interacting with Services Model that is 
part of the Realizing a Service Oriented Architecture View and in the 
process, I've moved service description related model artifacts to the 
Service Description Model.
http://wiki.oasis-open.org/soa-rm/TheArchitecture/ServiceView/ServiceDescription

As part of the Information Model, in addition to the data model elements, 
I've added message model elements.  We need to discuss whether this is at 
too fine grain a level of abstraction or not for this RA.  Note that the 
section numbers are not really correct as the data-level model and 
message-level models should be subsets of the information model, but this is 
just a limitation of the Wiki and we can clean it up in the actual document.

I've been having a lot of flaky interactions with the Wiki today.  Hope it 
settles out soon.

Cheers...

 - Jeff
