The type=require dependency specifies a minimum version, not an exact version. So installing version X+1 doesn't violate the version dependency. > 4.

The incorporate dependency is a min and max dependency. There isn't any maximum-only dependency specification. Maybe that is what type=exclude is supposed to do. Bart?
