In [1] I proposed:

   font-variant-caps: normal | small-caps          /* '-' added */
   font-variant-digits: normal | oldstyle | lining
   font-variant-width: normal | proportional
   font-variant-swash: normal | swash
   font-variant-ligatures: normal | standard | alternate

It seems that our approach is similar, although I belive that using
'font-variant' as a shorthand property is beneficial. This is all
about variants, no?
