Thank you, thank you. I hadn't picked up on this. The naming
conventions have always confused me, since there is a Fontspec feature
"Alternate" and "alternate" is also an option within the "Style"
feature, while stylistic sets were "Variants."
Style=Alternate and Alternate=0 are synonyms (for historical reasons).
The reason the naming scheme is so chaotic is that it was first written
to support Mac OS X AAT fonts (this was before XeTeX supported
OpenType!) and the OpenType support slowly merged with and then
supplanted the original purpose of the package.
I'm trying to document OpenType font features now with clear reference
to the actual feature tag, but I'm aware some of my terminology still
needs to be updated. Please do tell me if you find an unclear paragraph
(or twenty) in the manual and I'll do what I can to clear things up.
If clearer terminology could be found for all this, it would be a real
improvement.
For the hypothetical fontspec v3.0, I would like to totally revisit all
of the feature names (while supporting backwards compatibility of
course) but it's a big job for not much reward :)
It might also be useful for advanced users to be able to type
\fontspec[ss01,hlig,cwsh]{...}
That's certainly much easier to achieve!
In the last couple of days I have been thinking about using the
Character Variant feature (cv01-cv99) rather the stylistic alternate
feature for accessing glyphs such those I referred above. I haven't
gotten very far with this, but it might be something to add. (Does
anyone know of examples of this in use?)
I only just heard about these new features, too. I would also like to
see some examples -- I assume that a feature name like
CharacterVariant=0/1/2/3/4...
would be fine for fontspec?
Thanks,
Will
