How to create an NHibernate mapping file for a multi-valued component that is a unique set of columns?

I use NHibernate and Fluent NHibernate to create a mapping file for a domain object (although I don't care if the response uses free NHibernate or xml hbm syntax). And I'm having trouble figuring out how I indicate that the set of columns representing the component in the domain object is unique.

Here's the domain object:

public class SpaceLocation
{
        public SpaceCoordinate Coordinates { get; set; }
        public SpaceObject AtLocation { get; set; }
}

and here is the component I'm having problems with:

public struct SpaceCoordinate
{
        public int x { get; set; }
        public int y { get; set; }
        public int z { get; set; }
}

Do not worry about SpaceObject AtLocationfor the purposes of this quesiton.

So, I know how to make a component from SpaceCoordinate, but I want to make sure that there are no duplicate inserts of the same set of coordinates. To do this, I want to make the component unique.

, , , :

public class SpaceLocationMap : ClassMapWithGenerator<SpaceLocation>
    {
        public SpaceLocationMap()
        {

            Component<SpaceCoordinate>(x => x.Coordinates, m => 
            {
                m.Map(x => x.x);
                m.Map(x => x.y);
                m.Map(x => x.z);
            });
        }
    }
