    Gil -
    
    1-3: the consumer MUST explicitly create entities (transient or
    persistent). It can decide to create sessions explicitly if it wants to
    share them amongs entities, otherwise it can let the producer create
    sessions on the fly.
    4: the decision to have multiple entities per session is up to the consumer
    who make this choice based on the producer's metadata. e.g think of
    portlets that form a shop together. These would want to share a session
    with each other. But the consumer could decide to have two shops of the
    same type on the same page. Then there would be two sessions and only the
    consumer could know what portlet shares what session.
    5: The consumer should create a session before issuing a getFragment call.
    The entity is created whenever necessary.
    6: A Session is a bucket that holds some data (physically on the provider)
    and times-out after a while. A transient entity is a remote portlet that
    does not store any data in a DB.
    
    Hope that helped.

    Carsten, could you clarify some things for me?
    
    1. If sessions and entities are orthogonal, what SHOULD the Consumer do?
    2. SHOULD it create a transient entity _and_ a session?
    3. MUST it do so?
    4. Who gets to decide whether there are multiple entities per session or
    multiple sessions per entities?
    5. When SHOULD a Consumer create a session and when a transient entity?
    6. What _is_ a session, logically? What _is_ a transient entity?
