+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;

+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"

+// For URLs which use the schema `http`, `https`, or no schema, the

+//
+// * If no schema is provided, `https` is assumed.
+// * The last segment of the URL's path must represent the fully
+//   qualified name of the type (as in `path/google.protobuf.Duration`).
+// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+//   value in binary format, or produce an error.
+// * Applications are allowed to cache lookup results based on the
+//   URL, or have them precompiled into a binary to avoid any
+//   lookup. Therefore, binary compatibility needs to be preserved
+//   on changes to types. (Use versioned type names to manage
+//   breaking changes.)
+//
+// Schemas other than `http`, `https` (or the empty schema) might be
+// used with implementation specific semantics.

+// - Each annotation belonging to the service config (http,

+// - If an http annotation is inherited, the path pattern will be

+//     apis:
+//     - name: google.storage.v2.Storage
+//       mixins:
+//       - name: google.acl.v1.AccessControl
+//
+// The mixin construct implies that all methods in `AccessControl` are
+// also declared with same name and request/response types in
+// `Storage`. A documentation generator or annotation processor will
+// see the effective `Storage.GetAcl` method after inherting
+// documentation and annotations as follows:

+//       }
+//       ...
+//     }
+//
+// Note how the version in the path pattern changed from `v1` to `v2`.
+//
+// If the `root` field in the mixin is specified, it should be a

+//       mixins:
+//       - name: google.acl.v1.AccessControl

+// A Location identifies a piece of source code in a .proto file which

+// tools.
+//
+// For example, say we have a file like:
+//   message Foo {
+//     optional string foo = 1;
+//   }
+// Let's look at just the field definition:
+//   optional string foo = 1;
+//   ^       ^^     ^^  ^  ^^^
+//   a       bc     de  f  ghi
+// We have the following locations:
+//   span   path               represents
+//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
+//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
+//   [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
+//   [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
+//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+//
+// Notes:
+// - A location may refer to a repeated field itself (i.e. not to any
+//   particular index within it).  This is used whenever a set of elements are
+//   logically enclosed in a single code segment.  For example, an entire
+//   extend block (possibly containing multiple extension definitions) will
+//   have an outer location whose path refers to the "extensions" repeated
+//   field without an index.
+// - Multiple locations may have the same path.  This happens when a single
+//   logical declaration is spread out across multiple places.  The most
+//   obvious example is the "extend" block again -- there may be multiple
+//   extend blocks in the same scope, each of which will have the same path.
+// - A location's span is not always a subset of its parent's span.  For
+//   example, the "extendee" of an extension declaration appears at the
+//   beginning of the "extend" block and is shared by all extensions within
+//   the block.
+// - Just because a location's span is a subset of some other location's span
+//   does not mean that it is a descendent.  For example, a "group" defines
+//   both a type and a field in a single declaration.  Thus, the locations
+//   corresponding to the type and field and their components will overlap.
+// - Code which tries to interpret locations should probably be designed to
+//   ignore those that it doesn't understand, as more types of locations could
+//   be recorded in the future.

+// `FieldMask` represents a set of symbolic field paths, for example:
+//
+//     paths: "f.a"
+//     paths: "f.b.d"
+//
+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+//
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       y : 13
+//     }
+//     z: 8
+//
+// The result will not contain specific values for fields x,y and z
+// (their value will be set to the default, and omitted in proto text
+// output):
+//
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//       }
+//     }
+//
+// A repeated field is not allowed except at the last position of a
+// field mask.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily applies to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API.  In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+//
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+//
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+//
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+//     message Profile {
+//       User user = 1;
+//       Photo photo = 2;
+//     }
+//     message User {
+//       string display_name = 1;
+//       string address = 2;
+//     }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+//     mask {
+//       paths: "user.display_name"
+//       paths: "photo"
+//     }
+//
+// In JSON, the same mask is represented as below:
+//
+//     {
+//       mask: "user.displayName,photo"
+//     }
