  44   CHECK ME -- does prefix-set come from here ?
  45
  46   In a way, yes.  Actually, prefix-set is a property that is written
  47   by code of GregorianLigatureEngraver that is virtually invoked by a
  48   subclass like VaticanaLigatureEngraver.  The property is lateron
  49   read by the associated item class, such as VaticanaLigature.--jr
