Re: [office] Defining Alternative Glyphs

[Patrick Durusau <patrick@durusau.net>]

Rob,

Ah, so the question is one of how a format indicates some OpenType 
feature that should be invoked, assuming the application supports 
OpenType? In other words, how the application interacts with OpenType 
isn't our concern but simply indicating that it should and what 
information it should convey are.

Hope you are having a great day!

Patrick
