[NEW ISSUE] Remove Conversational interfaces functionality

[Mike Edwards <mike_edwards@uk.ibm.com>]

Target:        
        SCA Assembly specification
- CD01-Rev3

Description:

The Conversational interfaces capabilities
described in the Assembly specification (which affects several of the
other SCA specifications also) is a
complex feature that is not easy to implement, but neither does it provide
the
level of capability that is needed by
applications.  It should be removed from the assembly specification.

This is justified by the fact that much
of the capability of Conversational interfaces can be achieved by application
level data sent in the business interfaces
of services.

On the other hand, the more complex
requirements that have been called for (eg conversations spanning more
than
2 components) cannot be implemented
using the current capabilities and there is no simple way to progress from
the
2 component cases to the multi-component
cases.  It is likely that the complex cases really require something
very
different such as "Activity Sessions".


Proposal:

Remove Conversational interfaces from
the Assembly specification entirely.
