  //    separated by a slash (/). The name segment is required and must be 63
  //    characters or less, beginning and ending with an alphanumeric character
  //    ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and
  //    alphanumerics between. The prefix is optional. If specified, the prefix
  //    must be a DNS subdomain: a series of DNS labels separated by dots (.),

  //    Annotations that fails to meet these requirements will be rejected.
  //  - The '(*.)google.com/' and '(*.)googleapis.com/' prefixes are reserved
  //    for system annotations managed by Service Directory. If the user tries
  //    to write to these keyspaces, those entries will be silently ignored by
  //    the system.
