Maybe that's OK, but I don't yet understand the practical application of
a set of date/time values. Perhaps it would be clearer (to me at least)
to have some concrete examples?

For instance if a book has been published several times, it's publication date is a set of dates.

How do you square this with FRBR?

I wouldn't take seriously any proposed single entity with a publication set of dates.
Doesn't this mean that the entity covers a set of other things each with their own publication date?

Any other examples?
