Require a schema and an operation name to be given to each permit when created. The schema is of the table the read is executed against, and the operation name, which is some name identifying the operation the permit is part of. Ideally this should be different for each site the permit is created at, to be able to discern not only different kind of reads, but different code paths the read took. As not all read can be associated with one schema, the schema is allowed to be null. The name will be used for debugging purposes, both for coredump debugging and runtime logging of permit-related diagnostics.
