Custom metadata types are not yet available for Validation Rules. You still need to use Hierarchical Custom Settings if you want to have some configuration value affect a VR.


As of Spring '18 you can use Custom metadata types in Validation rules. Its available from 11th Feb 2018 in all Orgs and is already available in a few sandboxes to try out.
