Summary0009502: Clarify when the first notification is sent for a subscription.
Description

Part 4, section 5.13.1.1 states:
"When a Subscription is created, the first Message is sent at the end of the first publishing cycle to inform the Client that the Subscription is operational. "

I recall a discussion where this was modified so that for long subscriptions (e.g. 1 hour), the first update was sent as soon as data was available, to avoid a long delay on getting the first value.

If the spec was changed to support this, where is this stated, and should the quoted section above be modified?

We agreed this is best handled in a Client whitepaper where we suggest a shorter than requested publishing interval is set at first until an initial value is recieved for all items and then the publishing interval is changed to the longer (requested) interval e.g. 1 hour.
