Title: Message
I'm still trying to understand the interoperability
aspect of this.
Supposed a Consumer puts two entities on a
page.
If those two entities are different (one is a stock
portlet and the other is a weather portlet), then this is not an
issue.
If those two are two "instances" of the same entity and
don't share a session, they run independently so then this is not an
issue.
If those two "instance" are of the same entity and do
share a session, then the Producer may use this instanceKey to differentiate
between the data of the two... is this correct? If that's the case, if the
Producer MAY do this, how does the Consumer know whether it should allow/support
such a scenario, and how is interoperability guaranteed in such a
case?

My understanding is that this uniqueness is per
Consumer.

It's unclear to me from the text below in what context the
uniqueness
applies. It this per user? per page?

This text in the draft has been modified based on recent
decisions to:
entityInstanceKey: A unique, opaque
string the Consumer MAY supply as a
reference to this
use of the entity. This reference MAY be used by the
entity to properly separate data for multiple instances of the entity
within any Producer-defined data sharing mechanisms.
Since this reference
may be used as such a key, its
length MUST be less than 256 bytes and
Consumers
SHOULD keep it as short as possible.
There has also
been a suggestion to add a note that a Producer could use
this as a reference in place of generating a sessionID and that such a
use
will likely have a positive impact on the Consumer's
performance.

Title: Intent and scope of uniqueness of the
entityInstanceID in the
RuntimeContext
Document Section: 5.1.2
Description:
What is the intent of
entityInstanceID in RuntimeContext? The spec is
unclear about the difference between the producer-generated
entityHandle
and consumer-generated entityInstanceID.
It appears that the producer
will have to use both
entityHandle and entityInstanceID to uniquely
associate data with an entity. However, for producers not offering
registration, the consumer generated entityInstanceID
(along with
entityHandle) is not adequate for
guaranteeing uniqueness on the
producer end.
