Interesting, but I think that the OP wanted to use \frown as an accent,
\definemathaccent[topfake][top][offset=auto]
\definemathtopaccent[topfake][frowned]["2322]
\starttext
$ x + \frowned{4} = 10$
\stoptext
when you add in math-acc the offset option after the alignsymbol option
\ifcstok{\mathaccentparameter\c!alignsymbol}\v!yes
\s!nooverflow\space
\fi
\ifcstok{\mathaccentparameter\c!offset}\v!auto
\s!base\space
\fi
and someplace
\definesystemconstant {base}
(a patching exercise)
