Hebrew Layout Intelligence, which was developed by John Hudson of Tiro
Typeworks (who wrote this manual) and Ralph Hancock, is used for mark
positioning by a number of Hebrew fonts. Its guidelines govern their glyph
classes and chaining substitution rules. The fonts I know of that
explicitly implement it are SBL Hebrew, Ezra SIL, Keter YG, Keter Aram
Tsova.
