It also means that layout options that invoke more than one feature in a 
given font technology can be efficiently addressed in mark-up. An 
example would be the OTL GPOS optical bounds implementation, which 
involves separate features for left and right margins but which would 
sensibly be addressed by a single layout tag in a mark-up language.
