Agree. The properties weren't conceived as a closed enumeration, and 
defining in the schema.org domain doesn't seem appropriate.

Wasn't the idea of a registry of values floated earlier in the process?

I'm with Dan on this. In practice there are lots of existing values and
the potential for many future values; it's not feasible to have a fixed
enumeration that encompasses them all.
