I believe that we want this.

The scope of what property functions are capable of is essentially
unrestricted, so I don't think it's possible to really describe what
these functions do. However, it should be possible to obtain a list of
properties that fall into this category. As a user I would find that
useful in two ways:

1. I'd know that using this property in a query, or getting it back in
a result involves entailed data, and not just extensional data.
2. If I happen to recognize a property from the list, I will know that
a particular feature will be available to me.
