A good argument, and I think I agree, especially if there is a reasonable single value (usually string) to map it to.

But in every reference I can find, it appears that it still omits circle. This led me to here: http://forums.mysql.com/read.php?23,148162,152625#msg-152625 which offers a reasonably compelling argument for why "circle" is not a reasonable shape to discuss in geospatial contexts (loosely, because there's no consistent way to map that to a spherical coordinate system). Does this mean that perhaps ADM shouldn't *have* a "circle" primitive type? I assume that the ADM spatial types are intended for geospatial work, and if the consensus of the smart people is that "circle" doesn't fit in that world, perhaps we shouldn't include it either?
