+// Message that represents an arbitrary HTTP body. It should only be used for
+// payload formats that can't be represented as JSON, such as raw binary or
+// an HTML page.
+//
+//
+// This message can be used both in streaming and non-streaming API methods in
+// the request as well as the response.
+//
+// It can be used as a top-level request field, which is convenient if one
+// wants to extract parameters from either the URL or HTTP template into the
+// request fields and also want access to the raw HTTP body.
+//
+// Example:
+//
+//     message GetResourceRequest {
+//       // A unique request id.
+//       string request_id = 1;
+//
+//       // The raw HTTP body is bound to this field.
+//       google.api.HttpBody http_body = 2;
+//     }
+//
+//     service ResourceService {
+//       rpc GetResource(GetResourceRequest) returns (google.api.HttpBody);
+//       rpc UpdateResource(google.api.HttpBody) returns
+//       (google.protobuf.Empty);
+//     }
+//
+// Example with streaming methods:
+//
+//     service CaldavService {
+//       rpc GetCalendar(stream google.api.HttpBody)
+//         returns (stream google.api.HttpBody);
+//       rpc UpdateCalendar(stream google.api.HttpBody)
+//         returns (stream google.api.HttpBody);
+//     }
+//
+// Use of this type only changes how the request and response bodies are
+// handled, all other features will continue to work unchanged.
