Is there a word for a simple polygon with simple polygonal holes in it? eg: http://www.google.co...vh=148&hovw=312

I know there's a word for an annulus (http://en.wikipedia....8mathematics%29), for instance.

It just seems to come up enough in computational geometry that I'd be surprised if there wasn't a word for it, or at least a more compact way of saying it than "simple polygon with simple polygonal holes" or even "simple polygon with holes".

I only know of 'complex' polygon to describe a polygon which is not simple (which includes your polygon as it having a hole makes it not simple).
"Complex" allows self intersection, though.

"Perforated polygon" seems to be a popular name in the realm of spatial databases (http://www.google.co..._gc.r_pw.&cad=b)
