-        # used by [gRPC](https://github.com/grpc). The error model is designed to be:
+        # used by [gRPC](https://github.com/grpc). Each `Status` message contains

         #
-        # - Simple to use and understand for most users
-        # - Flexible enough to meet unexpected needs
-        #
-        # # Overview
-        #
-        # The `Status` message contains three pieces of data: error code, error
-        # message, and error details. The error code should be an enum value of
-        # google.rpc.Code, but it may accept additional error codes if needed.  The
-        # error message should be a developer-facing English message that helps
-        # developers *understand* and *resolve* the error. If a localized user-facing
-        # error message is needed, put the localized message in the error details or
-        # localize it in the client. The optional error details may contain arbitrary
-        # information about the error. There is a predefined set of error detail types
-        # in the package `google.rpc` that can be used for common error conditions.
-        #
-        # # Language mapping
-        #
-        # The `Status` message is the logical representation of the error model, but it
-        # is not necessarily the actual wire format. When the `Status` message is
-        # exposed in different client libraries and different wire protocols, it can be
-        # mapped differently. For example, it will likely be mapped to some exceptions
-        # in Java, but more likely mapped to some error codes in C.
-        #
-        # # Other uses
-        #
-        # The error model and the `Status` message can be used in a variety of
-        # environments, either with or without APIs, to provide a
-        # consistent developer experience across different environments.
-        #
-        # Example uses of this error model include:
-        #
-        # - Partial errors. If a service needs to return partial errors to the client,
-        #     it may embed the `Status` in the normal response to indicate the partial
-        #     errors.
-        #
-        # - Workflow errors. A typical workflow has multiple steps. Each step may
-        #     have a `Status` message for error reporting.
-        #
-        # - Batch operations. If a client uses batch request and batch response, the
-        #     `Status` message should be used directly inside batch response, one for
-        #     each error sub-response.
-        #
-        # - Asynchronous operations. If an API call embeds asynchronous operation
-        #     results in its response, the status of those operations should be
-        #     represented directly using the `Status` message.
-        #
-        # - Logging. If some API errors are stored in logs, the message `Status` could
-        #     be used directly after any stripping needed for security/privacy reasons.

+        # A `Policy` is a collection of `bindings`. A `binding` binds one or more
+        # `members` to a single `role`. Members can be user accounts, service accounts,
+        # Google groups, and domains (such as G Suite). A `role` is a named list of

+        # to `true`. A condition can add constraints based on attributes of the
