Are different versions of the same event unique?

The consensus (so far, at least) appears to be "no", and, practically, that's something I agree with.

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.

Cheers,

John
