Hi Frank,

Thanks for the feedback.

For the scenarios we were setting out to define in the CM 2.0 spec, there 
wasn't a pressing need for exposing the entire workflow.  The status 
property for CM 2.0 is more intended as an informational field, much like 
dc:title.   The state predicates are used to define the overall status of 
a change request.

Do you have some integration scenarios where we would need to expose the 
workflow?  Do you see this workflow being exposed as a read-only 
"informative" resource only or also a model to transition states?

Thanks,
