Hmmm, thinking about the mathematical definition of "product", it would seem
to me that the "product" would be some sort of representation of all
*possible* combinations of unique events and unique individuals; rather than
just the tiny, tiny, tiny subset of those that ever existed, and the even
tinier, tinier, tinier susbset that have actually been documented.

In database-speak, an Occurrence is simply a many-to-many join between
Events and Individuals, with a few additional properties.

...which is what I *used* to use the word "intersection" for.

It reminds me of the time when, as a young undergrad, I was informed that I
could no longer use the word "significant" in the sense of "important"....
