I have been experimenting with Janus, and using the automatic schema generation, metaproperties work as expected. However, when I set `schema.default=none` in the conf and define my own schema, metaproperties seem to quit working--metaproperty data is no longer returned in the Gremlin Server response. How should metaproperties be defined in the schema? I can't seem to find this information in the documentation. I can provide example schema definitions if necessary.

Thanks,

Dave
