ok, *.parameters probably carries the same info but for the rest you
cannot assume that the context font handler (plus the derived generic
one) will limit itself to that subset; in a similar fashion there is a
difference between what context keeps track of and stores and the raw
loaded otf font data
(in other words: cross macro package has a limited meaning)
