I would like to create stylistic sets that allow diacritics to be at a different distances from the letter they're attached to.
I'm new to the mark feature and haven't found a lot of resources around it. How would I use a different mark feature definition in a stylist set? E.g. ss01 causes all anchors defined by the mark feature to be at 500 units from the baseline, ss02 moves them to 750. What would be the syntax, if this is even the right way to go about it. If not, how else could I accomplish this that doesn't involve creating alternate glyphs?
