  optional EncryptedData encrypted = 1;

  // To add new datatype-specific fields to the protocol, extend
  // EntitySpecifics.  First, pick a non-colliding tag number by
  // picking a Cr-Commit-Position of one of your past commits
  // to src.chromium.org.  Then, in a different protocol buffer
  // definition, define your message type, and add an optional field
  // to the list below using the unique tag value you selected.
  //
  //  optional MyDatatypeSpecifics my_datatype = 32222;
  //
  // where:
  //   - 32222 is the non-colliding tag number you picked earlier.
  //   - MyDatatypeSpecifics is the type (probably a message type defined
  //     in your new .proto file) that you want to associate with each
  //     object of the new datatype.
  //   - my_datatype is the field identifier you'll use to access the
  //     datatype specifics from the code.
  //
  // Server implementations are obligated to preserve the contents of
  // EntitySpecifics when it contains unrecognized fields.  In this
  // way, it is possible to add new datatype fields without having
  // to update the server.
  //
  // Note: The tag selection process is based on legacy versions of the
  // protocol which used protobuf extensions. We have kept the process
  // consistent as the old values cannot change.  The 5+ digit nature of the
  // tags also makes them recognizable (individually and collectively) from
  // noise in logs and debugging contexts, and creating a divergent subset of
  // tags would only make things a bit more confusing.
