Google API Policy Annotation
This message defines a simple API policy annotation that can be used to
annotate API request and response message fields with applicable policies.
One field may have multiple applicable policies that must all be satisfied
before a request can be processed. This policy annotation is used to
generate the overall policy that will be used for automatic runtime
policy enforcement and documentation generation.
Specifies the required permission(s) for the resource referred to by the
field. It requires the field contains a valid resource reference, and
the request must pass the permission checks to proceed. For example,
"resourcemanager.projects.get".
Selects one or more request or response message fields to apply this
FieldPolicy.
When a FieldPolicy is used in proto annotation, the selector must
be left as empty. The service config generator will automatically fill
the correct value.
When a FieldPolicy is used in service config, the selector must be a
comma-separated string with valid request or response field paths,
such as "foo.bar" or "foo.bar,foo.baz".
