[tdwg-content] Occurrences, Organisms, and CollectionObjects: a review

I agree with Paul that the new proposed DwC class expands the scope of "CollectionObject" from what it has traditionally been. I'm just not sure any of the alternative terms are any better. Basically, we're talking about elevating "collectionObject" to a superclass of what it used to be. Everything ypou list below falls within scope of my understanding of the new (sensu lato) definition of "collectionObject". Now, one could argue that we keep "collectionObject" for the traditional (sensu stricto) meaning and come up with another term for the superclass. But I can't think of another term that would adequately represent the superclass, and "preservedSpecimen" works well for the subclass (=traditional "collectionObject"). I originally liked "voucher" because I use the term "virtual voucher" for photographic/videographic evidence of organisms. But I agree with Steve's comment that "voucher" probably has an even more explicit implication of "preservedSpecimen" than "collectionObject" does.
