Let $X$ be an equidimensional variety of dimension $n$ over a field that can be covered by open subvarieties of certain intersections of $N-n$ hypersurfaces in $P^N$ (for a large enough $N$; we consider set-theoretic intersections). Then $X$ can be called locally a set-theoretic complete intersection; this term sounds poorly and does not seem to be standard.
Is there a better term? How would you call $X$ if it is locally an intersection of $N-n+c$ hypersurfaces in $P^N$?
Upd. What do you think about "(locally?) requires only $c$ extra equations"?
