Are different versions of the same event unique?

> However: I don't think this is clear from the VOEvent standard. It tells us that an IVORN is used to resolve a particular "VOEvent packet", and (although I'm not sure it's plainly stated), my reading is that a "packet" is a specific representation, rather than the information contained within. In other words, while I agree with the views expressed here, I certainly don't think the answer is necessarily immediately obvious.

It 's a fair point. Which leads us to why anyone would want to do something this fundamentally broken in the first place?
