> The actual behavior of UDTs, now under construction, does not conform to the 
> spec. The spec says that you can't CAST to or from UDTs. This is probably too 
> harsh. We should allow the following CAST
>   cast ( null as udtType )
> I also think that we should allow at least the implicit casting of subtypes 
> to supertypes since Java gives us the ability to discover the type graph. See 
> Knut's comment on DERBY-651 on Dec 11, 2009.
