  55   CHECK ME -- does prefix-set come from here ?
  56
  57   In a way, yes.  Actually, prefix-set is a property that is written
  58   by code of GregorianLigatureEngraver that is virtually invoked by a
  59   subclass like VaticanaLigatureEngraver.  The property is lateron
  60   read by the associated item class, such as VaticanaLigature.--jr
