// * The version is implicit - it is only used for V1 leaves currently.

// * the leaf_type is also implicit: There's exactly one leaf type and no

// new types are planned.

|
// * The timestamped_entry's |timestamp| and |extensions| fields are directly
|
|
// accessible.
|
|
// * The timestamped_entry's entry_type can be deduced from |signed_entry|.type
