// ResourceDescriptor annotates a resource message (either by means of a

// resource's schema, the resource type, and the pattern of the resource name.
//
// Example:
//
//   message Topic {
//     // Indicates this message defines a resource schema.
//     // Declares the resource type in the format of {service}/{kind}.

// live under multiple parents.

//
//   message LogEntry {

//       type: "logging.googleapis.com/LogEntry"
//       pattern: "projects/{project}/logs/{log}"
