That is my intent, unfortunately, the examples you give don't work.
(The FSESelector gets created, but the simile fresnel code tries to
cast it to a TypeSelector before adding it to an internal hash table.)
The fresnel spec says that those selectors can only be used with
fresnel:instanceLensDomain, not fresnel:classLensDomain.

I tried that, and it worked after fixing a lot of issues in the
fresnel code. (It's very slow, though; it has to select every resource
in the system and then check if the selected resource is in the list.
