[Developers] A or B? Our problem with owners of stuff.

A typical solution is to create a new type ("thing owner") which you can then co-type with whatever makes sense for the context. We have quite a few types that work like this already: Aircraft Owner, Brewery Owner, etc. Actually, we're about to introduce some new types to the business domain: Asset, Asset Owner, and Asset Ownership (a mediator that also includes a percentage ownership), which is a slightly more elaborate and generic variation on that pattern.

Subject: [Developers] A or B? Our problem with owners of stuff.

We're messing with a situation where a thing can be owned by a person
*or* a company/organisation/whatever.  So we created a property on our
type called "owner" and then found ourselves wondering how to specify
this.

So what we want is some way to make a property be "either type A or B"
(or C, D, E).

Can we do that?
