 /**
+ *
+ *
  * 
  * The `Status` type defines a logical error model that is suitable for
  * different programming environments, including REST APIs and RPC APIs. It is
- * used by [gRPC](https://github.com/grpc). The error model is designed to be:
- * - 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][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.
+ * used by [gRPC](https://github.com/grpc). Each `Status` message contains
+ * three pieces of data: error code, error message, and error details.
+ * You can find out more about this error model and how to work with it in the
+ * [API Design Guide](https://cloud.google.com/apis/design/errors).
  *

   /**
+   *
+   *
    * 
    * The `Status` type defines a logical error model that is suitable for
    * different programming environments, including REST APIs and RPC APIs. It is
-   * used by [gRPC](https://github.com/grpc). The error model is designed to be:
-   * - 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][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.
+   * used by [gRPC](https://github.com/grpc). Each `Status` message contains
+   * three pieces of data: error code, error message, and error details.
+   * You can find out more about this error model and how to work with it in the
+   * [API Design Guide](https://cloud.google.com/apis/design/errors).
    *

+ * 
+ * This message defines the standard attribute vocabulary for Google APIs.
+ * An attribute is a piece of metadata that describes an activity on a network
+ * service. For example, the size of an HTTP request, or the status code of
+ * an HTTP response.
+ * Each attribute has a type and a name, which is logically defined as
+ * a proto message field in `AttributeContext`. The field type becomes the
+ * attribute type, and the field path becomes the attribute name. For example,
+ * the attribute `source.ip` maps to field `AttributeContext.source.ip`.
+ * This message definition is guaranteed not to have any wire breaking change.
+ * So you can use it directly for passing attributes across different systems.
+ * NOTE: Different system may generate different subset of attributes. Please
+ * verify the system specification before relying on an attribute generated
+ * a system.

+   * An attribute is a piece of metadata that describes an activity on a network

+   * an HTTP response.
+   * Each attribute has a type and a name, which is logically defined as
+   * a proto message field in `AttributeContext`. The field type becomes the
+   * attribute type, and the field path becomes the attribute name. For example,
+   * the attribute `source.ip` maps to field `AttributeContext.source.ip`.
+   * This message definition is guaranteed not to have any wire breaking change.
+   * So you can use it directly for passing attributes across different systems.
+   * NOTE: Different system may generate different subset of attributes. Please
+   * verify the system specification before relying on an attribute generated
+   * a system.

 // The `Status` type defines a logical error model that is suitable for
 // different programming environments, including REST APIs and RPC APIs. It is
-// 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
+// three pieces of data: error code, error message, and error details.
 //
-// - 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][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.
+// You can find out more about this error model and how to work with it in the
+// [API Design Guide](https://cloud.google.com/apis/design/errors).
