Description:

The MixedOutcome is not tested for in the interoperability scenarios 
(AtomicOutcome is). This either needs to be fixed, with some scenarios 
added, or we should remove the capability. I haven't seen any good 
arguments for why we should have this protocol within the 
BusinessActivity specification. If there is a requirement, then it seems 
more appropriate for a separate model (i.e., specification) to host this.

Proposed resolution:

Remove MixedOutcome
