![Nathan McKinley](/assets/img/avatar_default.png)
- Fetch Zone attribute any place where it *was* being fetched from the schema by combination schema / provider-level attribute. - Allow region to be unspecified if zone is specified. - Switch one example to using provider-level zone as an example. - Make provider-level zone optional. (Individual resources will fail if they can't find a zone.) - Add tests for getZone and getRegion.
