I think it's ok for now if you want to have this conversational boolean 
flag on Interface, but according to the SCA spec, "conversational" is 
really a policy intent which I believe should be applied to the whole 
contract (including the interface and the corresponding callback 
interface, if any). I had put an isConversational flag on the first of 
Interface but had removed later it for this reason :) It's probably a 
good idea to add a //TODO to the code and/or a JIRA issue to mark that 
we'll need to make this change later.

Here's the relevant text from the SCA assembly spec:
This specification requires interfaces to be marked as conversational by 
means of a policy intent with the name "conversational".   The form of 
the marking of this intent depends on the interface type.  Note that it 
is also possible for a service or a reference to set the conversational 
intent when using an interface which is not marked with the 
conversational intent.  This can be useful when reusing an existing 
interface definition that does not contain SCA information.
