A description of how to encode ligature brackets in **kern spines.
Ligatures are are sequences of notes attached to each other in mensural music. When notating the music in modern notation, typically a bracket will be placed over the separated notes to indicate that the group of notes were originally notated in a ligature.
Use *lig to start a ligature bracket, and *Xlig to end a
