Hi, I was reading the source code of this project and I found there is

Namespace

term appear somewhere in it I think

Namespace

has the same semantic as the

ObjectType

Here is [one part I found](https://github.com/authzed/spicedb/blob/21210538ae1df9cd603cdf7f111d7b739d6ca949/internal/services/v1/permissions.go#L89-L92), am I right?
