Subject: Re: [wsrp] Few clarifications on stateChange flag and consumer-managedstate


Rich,

I agree with that interpretation. But the spec does not specify that the 
  producer MUST NOT return a new portletHandle when readRead is supplied 
by the consumer.

In the case of registration, the producer MUST NOT return new 
registrationHandle in response to a modifyRegistration request.

I think both these are required since consumers may be using the handles 
as keys in databases.
