OK. I wasn't aware that this was possible. Very neat!

Looking at coding in  xltxtra.sty , what is the purpose of
lines like the following? (3 instances, connected with
super/subscripts and fractions)

        \c at zf@script 1818326126\relax

It looks like these are setting a particular value for a counter,
but where is this counter ever used?
