// `Context` defines which contexts an API requests.

// Example:
//
// context:
// rules:
// - selector: "*"
// requested:
// - google.rpc.context.ProjectContext
// - google.rpc.context.OriginContext
//
// The above specifies that all methods in the API request
// `google.rpc.context.ProjectContext` and
// `google.rpc.context.OriginContext`.
//
// Available context types are defined in package
// `google.rpc.context`.

// This also provides mechanism to allowlist any protobuf message extension that
// can be sent in grpc metadata using “x-goog-ext--bin” and
// “x-goog-ext--jspb” format. For example, list any service
// specific protobuf types that can appear in grpc metadata as follows in your
// yaml file:
//
// Example:
//
// context:
// rules:
// - selector: "google.example.library.v1.LibraryService.CreateBook"
// allowed_request_extensions:
// - google.foo.v1.NewExtension
// allowed_response_extensions:
// - google.foo.v1.NewExtension
//
// You can also specify extension ID instead of fully qualified extension name
// here.
