Clarification of events_delivered from the past calls

The transmitter may reserve rights to deliver events on certain occasions such as (but not limited to) -

1. Receiver has not paid for SKU that the event is part of,
2. Receiver is not in the desired jurisdiction/compliance environment to receive the event

Suggested wording:
events_delivered

Transmitter-Supplied: An array of URIs identifying the set of events that the Transmitter SHALL include in the stream. This is a subset of the intersection of "events_supported" and "events_requested". A Receiver MUST rely on the values received in this field to understand which event types it can expect from the Transmitter.

This is a subset of the intersection of "events_supported" and "events_requested"

I feel the above statement suggests that it will always be a subset, which may not be true.

If you are referring to "A set is a subset of itself" principle to describe this, I feel it may not be clear to an ordinary reader.

If there's a mathematical term to specify the subset that isn't the "proper subset", then we can include that. In normative text, I prefer precision, but happy to consider opinions of other members. Perhaps we can say: "This is a subset (not necessarily a proper subset) of ..."
