Comment (by jinmei):

 It's quite  likely `LabelSequence` will stop holding a `Name` object
 directly (see #2086).  So I'd avoid relying on it.  Perhaps we should
 do it in a reversed way: move the current `Name::toText` logic to
 `LabelSequence`, which for now uses the internal data structure of
 `Name` (eventually changed to even lower-level representation).
 `Name::toText()` will create `LabelSequence` and call its revised
 toText().
